ABSTRACT:
A low part count momentary push-button assembly having an integral indicator lamp for indicating activation of a controlled circuit or device. The push-button assembly comprises a switch unit and indicator lamp mounted side-by-side on a central region of a printed circuit board, a push-button having a contact area disposed in axial alignment with the switch unit, and a light transmissive passage disposed in axial alignment with the indicator lamp, and a unitary interface element disposed intermediate the circuit board and the push-button. The interface element includes an integral sleeve for locating the indicator lamp in relation to the light transmissive passage of the push-button, and a cantilevered structure which is maintained in resilient engagement with the contact area of the push-button. The interface element snaps onto the circuit board, and the circuit board is snapped into a housing cavity. The push-button is retained in relation to the switch unit and indicator lamp by a housing element which closes the cavity.
