Technical Examples

A locking switch assembly includes a cam, a plunger, and a locking mechanism. The cam is rotatably attached to a frame assembly and an end of the plunger is constructed to follow a contour of the cam. The plunger is movable between a plunger first position and a plunger second position. A pin is biased against the plunger and movable between a pin first position and a pin second position and locks the plunger in the plunger second position when the pin is in the pin second position. A breakable arm prevents movement of the plunger from the plunger second position to the plunger first position unless a force above a selected amount is applied to the cam when the plunger is in the plunger second position.
