Precautions
Refer to General Information.
Correct Use
Mounting
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 N·m {4 to 6 kgf·cm}.
Mounting Holes
When mounting on a metal surface, be sure to provide a Separa-
tor between the Switch and mounting plate.
Soldering
When soldering the lead wire to the terminal, first insert the lead
wire conductor through the terminal hole and the conduct solder-
ing.
Make sure that the temperature at the tip of soldering iron is
350°C max. Do not take more than 3 seconds to solder the switch
terminal, and do not impose external force on the terminal for 1
min after soldering. Improper soldering involving an excessively
high temperature or excessive solding time may deteriorate the
characteristics of the Switch.
