3 SWITCH TECHNOLOGY TECHNICL TERMS Butt Contacts Contacts which make at one point and maintain their initial relationship without further movement until they are opened. Wiping Contact moving contact mechanically arranged to slide across the fixed contact during pretravel and overtravel. Clearance Distance The distance in air between current carrying parts of opposite polarity or between any current carrying part and an earthed (grounded) metal plate to which the switch is attached. Creepage Distance The path along the surface of insulating material between current carrying parts of opposite polarity or between any current carrying part and an earthed (grounded) metal plate to which the switch is attached. Insulation Resistance Resistance as measured between the normally-open and normally-closed terminals, or between all terminals connected together and a metal plate to which the switch is mounted. In dry condition the value would be expected to be greater than 5000 megohms. Single Throw switch which provides an ON-OFF or OFF- ON function but does not change over from one conductor to another. Such switches are usualiy referred to as being «normaliy-closed only» or «normally-open only». C2 signifies «Normally-closed only»; C4 signifies «normally-open only». Switching Cycle One complete switching operation, from free position into overtravel and back through release position to free position. Mechanical life estimates reflect the number of switching cycles expected to be accomplished before operating characteristics become impaired. Switch Resistance The total resistance offered by a switch in a circuit, as measured from terminal, through mating contacts, to terminal. Transit Time The time taken by the moving contact in snap-action switch mechanism to move from one stable position to another. ELECTRICL RTINGS Recommended maximum electrical ratings are quoted for each product group. These ratings are based on the results of controlled, accelerated, laboratory-type tests and are regarded as safe working maxima for most applications. The performance of switches is, however, influenced by conditions pertaining on site e.g. frequency of operation, type of, amount of actuator travel used, temperature and humidity, etc. The characteristics of micro switches rely upon mechanisms having small contact separation. Because of this, it is always desirable to check on the arcing potential of your circuit and to suppress those elements which could cause excessive arcing. SWITCH LIFE The electrical life of a switch is dependent upon frequency of operation, the on-off ratio of operation, the nature of the, arc suppression and other circuit details, the amount of actuator travel used, ambient humidity and temperature and many other site factors, none of which is within the switch manufacturers competence to control. Electrical life test information relates to laboratory controlled tests. Individual assessments, for specific applications where all relevant data is available, are possible and can be undertaken by SI- Burgess Electronics upon request. For details of the mechanical life of individual switches, please refer to the appropriate specification sheet. 3

4 PPLICTION TECHNOLOGY Shock and Vibration If switches are likely to be subjected to shock or vibration, select models with the highest available actuating force. Switches in this Catalogue possess low mass mechanisms which are inherently resistant to shock and vibration. If practicable, the switches should be mounted in such a position that the line of acceleration is at right angles to the travel of the plunger. The maximum available overtravel should be used. Capacitive Loads These can generate very high inrush peaks and care should therefore be exercised to avoid contact welding. Direct Current Direct Current (DC) ratings are provided for each product group listed in this Catalogue. The values stated should not be exceeded if destructive arcing and contact welding are to be avoided. Some form of arc suppression is recommended when switches are used in DC circuits containing inductive devices wired in series with the switch and the supply. Five common arc suppression circuits which may be used to alleviate the effects of arcing on the switch contacts are shown here. The values of the components used depend on circuit conditions. Inductive Loads Electrical Ratings Tables included in this Catalogue provide data for switches used to control inductive circuits at a power factor of 0.5 Lamp Loads Because of the very high inrush currents associated with incandescent lamps, applications should be subject to individual assessment. Logic Circuits To provide reliable switching, the use of gold plated contacts is recommended. Three types of construction are used: U: signifies gold plating on nickel underlay GP: indicates gold-plated silver contacts GPX: relates to gold-plated cross point contacts Installation recommendations The following notes are intended merely to stress the most important and general aspects of good switch installation procedure and to provide some helpful additional information. Safety Considerations Installation should only be carried out by competent personnel. Position and Operation Operating position is the significant factor to consider when positioning any snap-action switch. The actuating medium must be able to operate the switch through this position into overtravel and then to retract far enough to allow the switch to regain its free position. Mounting Side mounting switches should be mounted on smooth, firm, flat surfaces using the recommended size of screw. void over-tightening the screws. For added security, they should be locked using epoxy resin. Do not attempt to enlarge switch mounting holes and avoid over stressing the switch. Use insulating material between switch and metallic plates to increase clearance on switches with open terminals. Mounting holes and Screw sizes Nominal hole Metric Unified Thread Diameter Screw Screw (mm) (in) M 2 # M 2.5 #4 Mounting-Screw Torque The following provides guidance when using mild steel screws M 2 or # 2 screws 0.12 Nm M 2.5, M3 or # 4 screws 0.5 Nm Connections When soldering, avoid over-heating any part of the switch insulation. In certain circumstances, it may be advisable to use a heat shunt. For optimum mechanical strength, the conductor should be wrapped round the tip of the terminal taking care to avoid loose strands of wire. The soldering iron bit should be applied to the end of the terminal while simultaneously applying solder. Remove the iron as soon as the solder has wetted the conductor and terminal end. soldering iron bit temperature of 370 C applied for a maximum of 2-3 seconds should be adequate. 4

5 CONTCT MTERILS Gold Gold plated contacts are recommended for switches to be used in low voltage control or logic circuits, especially when long periods of inactivity are envisaged. Gold flash, a thinner deposit, is applied to certain switch terminals to ensure good solderability even after prolonged storage. How to determine the contact material for SI XG/XC-series only The selection of the appropriate contact material will depend on a number of factors: Silver-cadmium oxide contacts Silver-cadmium oxide (gcdo 90/10) contacts should be used where high inrush current peaks (30 or more) are switched on as they tend to weld less at high current s. They can resist peaks of 80 or more for several ms provided that they are used with a SI- Burgess Snap-ction Switch with high operating and contact force (80cN in the free position and total-travel position). t high breaking capacities, switches fitted with such contacts have about 50% longer life expectancy than those fitted with pure silver contacts. Normally, silver-cadmium oxide contacts are not suitable for voltages under 50V. current and voltage resistive or inductive inrush current peak frequency of switching operations atmospheric conditions required switching reliability Pure silver contacts (standard) SI-Burgess Snap-ction Switches are normally equipped with pure silver contacts (g999). These are suitable for most applications and have satisfactory electrical and thermal properties. Gold-plated contacts Gold-plated contacts (4 µm) are used for low currents of a few m and voltages below about 20 V (for DC and C) and for sulphurous atmospheres. They are unsuitable for higher breaking capacities. 5

6 SERVICE RECOMMENDTIONS Maintenance SI-Burgess switches are not usermaintainable but they should be kept in a reasonably clean, paint-free condition, especially in the actuator area. Regular checks should be made on mounting security and on the actuating medium to switch actuator relationship. SWITCH CTUTION Simple actuating plunger ctuating plungers should be operated in the direction of their axis. The plungers of the switch series may also be actuated laterally by cams at a recommendet maximum angle of 30. max. 30º Switch Life The effective life of any switch will depend upon the model selected, the number and frequency of operations, circuit conditions and the severity of the environment. Switch replacement should be a matter of routine. ctuation by sliding cams. ctuating levers ll types of Iever (straight, roller, cam-follower) fitted to SI-Burgess Snap-ction Switches are made of stainless steel. Cam-follower levers are particularly well suited for use with plastic actuating cams. If roller or cam-follower levers are approached in the reverse direction, care must be taken to ensure that the angle of approach is small enough not to jam the lever. ctuation by cams brupt actuation or release of levers shortens life of the, switches. For this reason cams should preferably provide a continuous movement. Ideally they should be of cycloidal form. Long roller lever with continuous actuation. 6

7 HELTH ND SFETY SI-Burgess Electronics have ensured, so far as it is reasonably practicable, that their products as described in this Catalogue or in other current Company publications, or as specified on Company Installation Drawings, have been so designed and constructed as to be safe and without risk to health when installed by suitably qualified personnel in accordance with relevant legislation, codes of practice, regulations (including IEE Wiring Regulations), the installation recommendations offered by the Company and the accepted rules of the art. Their usage should be confined within the ratings, limitations and parameters of application indicated in this Catalogue and elsewhere. SI-Burgess Electronics or their representatives are available at all times to provide further information and guidance. ENVIRONMENTL PROTECTION Protection Classifications The catalogued range of SI-Burgess switches is covered by just four codes. IP40 (no corresponding NEM type) dequate protection against solids such as probing fingers and small wires. Liquids, however, can gain access and, unless externally protected, the switches should be mounted in dry or well-sheltered positions. IP54K (corresponding generally with NEM type 4) Good protection against solid foreign bodies and liquid spray of an intensity which could be expected to be emitted from a watering can. The spray may come from any angle. Switches may be used out of doors if sheltered from the worst of the elements or on factory machines subjected to normal washing down procedures. IP6K5 (corresponding generally with NEM type 13) Complete protection against solids, including dust, and against liquid splashing of the severity to be expected if the switch was turned round and round under a cold water tap. This IP code is nominated in DIN specifications for limit switches. IP6K7 (corresponding generally with NEM type 6) Similar protection to IP65 but this code is reserved for switches which are factory sealed and pressure tested. Switches should not be immersed in any liquid. Working Temperatures For details of the working temperatures applicable to individual types, refer to the appropriate specification sheet. Special versions suitable for temperatures outside these ranges are possible. Details from SI-Burgess Electronics on request. ll quoted temperatures assume stable operation. They do not imply an ability to withstand excessive cycling within the range.

By using the twin-shot process, all four parts of the housing, comprising two different plastics, are produced in a single moulding. The twin-shot process is a dual-component technology which uses a two-stage injection moulding process first to produce the hard plastic shell and then the soft sealing aera. By selecting appropriate materials, both plastic form a molecular bond. The result is a completely sealed connection, without adhesive or mechanical joints. This new process guarantees maximum reliability, even under the toughest conditions. ssembly is fully automatic, including testing, and enables fault-free production at minimal cost NO2 C NO1 4.1 ±0.2 (.161 ±.008) 2.7 ±0.1 (.106 ±.004) 0.5 (3x) (.02) 13 ± 0.3 (.512 ±.012) 5 ±0.2 (.197±.008) 3 (3x) (.118) 5.5 (.216) 74
