1. A seesaw type switch comprising:
- a case having a bottom surface;
a stationary contact fixedly connected to said bottom surface;
a movable contact mounted on said bottom surface such that said movable contact is slidable along said bottom surface between and engaged position in which said movable contact electrically connects with said stationary contact, and a disengaged position in which said movable contact is electrically isolated from said stationary contact;
a first lever pivotally supported by said case, said first lever having a top surface and a first protrusion including an end, the end of said first protrusion engaging said movable contact such that when said first lever is in a first pivoted position, said moving contact is in said engaged position, and when said first lever is in a second pivoted position, said moving contact is in said disengaged position;
a cover fixedly connected to said case over said first lever; and
a second lever pivotally supported by said cover, said second lever having a second protrusion extending through said cover and engaging said top surface of said first lever such that when said second lever is in a third pivoted position, said first lever is in said first pivoted position, and when said second lever is in a fourth pivoted position, said first lever is in said second pivoted position.
