Abstract
An electrical switch assembly comprises a first, domed, flexible contact member plus at least one second, flexible, finger-type contact member positioned under the first contact member in normally spaced relation thereto. Actuator means are provided for pressing the first, domed contact member into contact with the second contact member to actuate the switch assembly. In accordance with this invention the second, flexible, finger-type contact member defines an end portion which is bent to permit increased-area contact with the first contact member when the first contact member is pressed into contact with the second contact member. This also provides improved wiping action between the first and second contacts as the increased-area contact is made and broken for removal of carbon build-up and the like.
