Frequently Asked Questions
How do I wire the ME-8107 switch for normally closed operation?
Connect your supply to the common terminal (COM) and route the load to the NC terminal. When the roller lever isn’t actuated, the NC contacts remain closed and open upon actuation.
Can I adjust the actuation point of the roller lever?
Yes. Loosen the lever’s mounting screw, rotate the adjustable roller arm to your desired angle or position, then retighten the screw to lock the lever in place.
What mounting hardware is required?
The switch uses two M4 screws spaced 56 × 21 mm apart. Use standard M4 nuts or screw assemblies to secure the switch onto your machine frame.
