Abstract
A single pole electrical switch of relatively thin overall dimension has a rocker provided on an off center axis in the circuit breaker housing, which rocker is adapted to slide a moveable contact across the upper ends of the fixed contacts to achieve opening and closing of these contacts. The moveable contact in the off position is spaced from one of the end walls of the switch case housing to allow provision for a third fixed terminal in a stepped portion of the bottom wall. The upper end of this third terminal is located in close proximity to the rocker so as to afford electrical connection with a resistor or other component of the lamp circuitry provided in the rocker.
Claims8
An electrical switch comprising:
- an upwardly open housing of generally rectangular configuration with spaced front and rear walls that are integrally connected to one another by end walls and by a bottom wall to define a cavity,
- a rocker having skirt portions that define axle projections received in openings defined in said front and rear housing walls, said rocker being pivotable on a rocker pivot axis and said skirt portions being moveable between said housing front and rear walls and defining a space therebetween,
- a moveable contact having a segment provided in said space between said rocker skirt portions,
- said moveable contact having projecting ears at said moveable contact segment in said space defined by said skirt portions, said ears being received in slots provided in said skirt portions to allow limited movement of said movable contact toward and away from said pivot axis of said rocker and to allow rocking movement of said movable contact on a second axis defined by said ears,
- at least first and second contacts in said housing bottom wall with upper ends provided inside said housing, said fixed contacts provided in said bottom wall being of identical geometry, said first fixed contact having its upper end spaced above an upper end of said second fixed contact and a single compression spring having a substantial portion retained by said rocker between said skirt portions and having a free end portion engaging said moveable contact segment for urging said moveable contact toward said upper ends of said fixed contacts,
- whereby pivotal movement of said rocker causes said moveable contact to pivot and slide across said upper end of said first fixed contacts and to selectively make contact with said upper end of said second fixed contact.
