ABSTRACT:
When the electromagnet (relay) is energized, the plunger is pulled into the coil against the bias of the plunger spring. The pin projecting laterally from the plunger is captive in the opening in the cam pivoted on the frame. The pin moves down and strikes a ramp portion in the cam and is deflected to the bottom of the notch where it impacts the cam and rotates it to a position in which the cam surface actuates the switch actuator. The internal switch spring acting on the actuator exerts force on the cam surface and cooperates with the contour to hold the cam in either position. When the coil is de-energized, the plunger moves out and the pin is deflected by the return guide surface of the frame to pass to the opposite side of the cam centerline and into position to actuate the cam in the opposite sense when the coil is again energized.
