Operation
1NO/1NC Contact (Snap-action)
If metal deposition between mating contacts occurs on the NC contact side, they can be pulled apart by the shearing force and tensile force
generated when part B of the safety cam or plunger engages part A of the movable contact blade. When the safety cam or plunger is moved in
the direction of the arrow, the Limit Switch releases.
