Abstract
Disclosed is an apparatus for use in opening bus doors and the like comprising a touch bar supported by having its ends received in a pair of housings within one or both of which is mounted a reciprocal electrical switch mechanism responsive to lateral movement of the touch bar in any direction relative to a housing containing the switch mechanism. Switch actuation is obtained by providing opposed concave surfaces in fixed association with the touch bar and associated housing with the surfaces operated by a round element, such as a ball. Any rolling of the ball from centered position causes parting movement of the elements defining opposed concave surfaces and linear movement of one of the elements useful for switch actuation.
