ABSTRACT:
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to an electrical switch.
2. Description of the Prior Art
Vehicles with electric power devices, such as windows, typically have a control system with several individual switches. Each switch has a manually engageable lever pivotable to actuate the device.
One known window switch structure is described in U.S. Pat. No. 5,598,918. The switch includes an actuator which is manually pivotable in opposite directions to engage and close electrical contacts for energizing the motor. The switch also includes an electrical contact which is rocked by the pivoting actuator to close a set of contacts in the switch. The electrical contact is made from metal.
SUMMARY OF THE INVENTION
The present invention is an electrical switch comprising spaced first and second contacts, and a rocking contact having first and second arms in electrical contact with each other. A support supports the rocking contact for rocking movement in opposite first and second directions. The first arm moves into engagement with the first contact when the rocking conactrocks in the first direction, and the second arm moves into engagement with the second contact when the rocking contact rocks in the second direction. The switch includes a member which pivots to effect rocking movement of the rocking contact in the first and second directions. The member pivots in one direction a first distance to cause the first arm to engage the first contact and pivots in the one direction a second distance beyond the first distance to cause the first arm to slide on the first contact.
