Also provide Switch is in the free position (FP). When the actuator is a time interval of at least five minutes between the first and operated from the crosswise direction of the Switch, make second reflow soldering processes to allow the Switch to sure that the corner of the operating body has a minimum return to room temperature. radius of R1. Heating the Switch continuously (without an interval) may cause the edges of the Switch to melt and degrade the characteristics. R1 min.

Consider this possibility with respect to the PCB particles may penetrate the interior of the Switch when usage conditions when designing or using the Switch. printed circuit boards are separated by cutting. Also, do not stack printed circuit boards that have Switches mounted on them. ●Application Environment (cid:129)Do not use the Switch in locations that are subject to toxic gas, ●Product Specification Details silicon gas, excessive dust, excessive dirt, high temperatures, This document provides only a partial list of specifications.
