Correct Use


•Apply operation force to the pin plunger in the direction it oper- ates.Applying forces laterally or from an oblique direction may damage the pin plunger.

•Use M3 mounting screws to mount the Switch. Tighten the screws to a torque of 0.4 to 0.6 Nm {4 to 6 kgfcm}.


•Terminal connectiion
When soldering the lead wire to the terminal, first insert the lead wire conductor through the terminal hole and then conduct soldering.
Complete the soldering at the iron tip temperature not exceeding 350°C within 3 seconds, and do not apply any external force for 1 minute after soldering. Soldering at a excessively high temperature or soldering for more than 3 s may deteriorate the characteristics of the Switch.
