Built-in Switch
The built-in switch has a direct opening mechanism
that forcibly separates the NC contact even when
there is contact deposit.
Cover
The cover, with a hinge on its lower part, can
be opened by removing the screw of the
cover, which ensures ease of maintenance
and wiring.
Safety-oriented Lever Setting

Grooves which engage the lever are cut in the lever and
rotary shaft to prevent the lever from slipping against the
rotary shaft.
There are resin-lever and metal-lever types.
