Abstract
A hook switch has a box-shaped body an an open end. Within the box-shaped body there is fixed at least one contact piece, and extending from the box-shaped body is an arm on which an actuator is rotatably mounted. A slider is received within the box-shaped body. This slider has a spring biased protrusion with a spherical top which extends through a hole in a cover of the box-shaped body and is engaged by the actuator and displaced against the spring bias. In the process, a movable contact piece mounted on the slider engages a corresponding fixed contact piece mounted within the box-shaped body.
