Abstract
A switching device for industrial equipment having at least one pair of contacts includes a transfer member rotatably mounted in the switching device. The transfer member is configured to receive a first force applied to the switching device in a first direction and to receive a second force applied to the switching device in a second direction. A rocker arm, rotatably mounted in the switching device, engages the transfer member to receive the first force over a first angle of rotation and to receive the second force over a second angle of rotation. The second angle of rotation is less than the first angle of rotation. A lever arm is pivotally mounted within the switching device. The lever arm engages the rocker arm to move between an Off position and an On position, and a plunger is actuated by the lever arm to selectively open and close the contacts.
