Abstract
An electrical switch includes a casing, first and second fixed contacts, and a moving contact lever having first and second parts for contact with the first and second fixed contacts, respectively. A spring resiliently biasses the lever into contact with both of the first and second fixed contacts. There is also a pushbutton movable between first and second positions to cause the lever to move into contact with and out of contact from the fixed contacts, respectively. The pushbutton and spring act upon the lever at respective positions that are offset from each other. The lever is pivotable by the pushbutton in one direction to separate the first part from the first fixed contact and, subsequently, in an opposite direction to separate the second part from the second fixed contact.
