Tighten the screws with 0.3 to 0.5 N m {3 to 5 kg cm} torque. To prevent loosening of the mounting screws, it is recommended that spring washers be used in combination with adhesive material for locking the screws. 2. Adjustment of the operating : With respect to the of the operating and the switch body, set the as indicated in the condition on the right. If this condition is exceeded, the mechanical and electrical performance will be impaired. In addition, the force applied by the operating should be in a perpendicular direction. Even if the pushbutton is used in the full total travel, there will be no influence on the life of the switch. Screw mounting type Free condition Snap-in mounting type Free condition More than 17 mm.9 inch switch More than.5 mm.571 inch Operation condition Operation condition 10 to 10.5 mm.394 to.413 inch switch 7.5 to mm.295 to inch 3. Confirming insulating distance: Before mounting and wiring, the insulating distance between s and between s and ground should be checked for assurance of proper distance. With respect to the connections, it is recommended that receptacles with insulating sleeves be used. Also, consideration should be given to the wiring not to apply force to the section normally. 4. Avoid using GW switches in the following conditions: Locations where hydrogen sulfide gas or other corrosive gases exist. Locations where gasoline, thinner, or other inflammable or explosive gases exist. Locations where there are dust and refuse. For operation where the perpendicular operating speed is less than /sec. For operation frequency of make/break exceeding 0 cpm. For ambient temperatures exceeding the range of 25 C to +5 C +13 F to +15 F. For ambient humidity exceeding 5% R.H. For use in a silicon atmosphere. 5. For use of 405 (1 Form Z type): For the type 405, the air distance between the N.O. and N.C. contacts is less than the required value of VDE. The N.O. and the N.C. contacts can carry only the same electric potential. 119
