Unless otherwise stated, a tolerance of ± 0.mm applies to all dimensions 2. No terminal numbers appear on the switches. To orient a switch in the bottom view position, turn it so that the terminals are on the up and down sides and the word OMRON is right-side up.

Solder at 260 ± C within five seconds and within two tries. Do not wash the switches. The switches may be damaged by solvents if either wiped off using solvents or immersed in solvents. Do not allow flux or flux foam to penetrate onto the component side of the PCB. Use a single-sided PCB with a thickness of 1.6 mm. The switches may be damaged due to instability or heat from soldering if other PCBs (other thickness or through holes) are used. If it is necessary to use another PCB, test the compatibility and processing in advance. The switches are not sealed and should be protected with a resin sheet as shown below when used in dust-prone environments. Keytop 12.±0.1 Six dia Resin sheets Switch
