A switch that can be installed within an aperture in a housing of an electronic device without obstructing the aperture via a port through the switch. In a particular application, the switch can be utilized in connection with a port of a microphone in a hearing aid. The switch is capable of being installed within an aperture in a faceplate of a hearing aid. The switch comprises a base having an aperture therein and two base electrical contacts, and an actuator having an aperture therein and an actuator electrical contact. The actuator is adapted to cooperate with the base to permit movement of the actuator to an open switch position and a closed switch position, wherein the actuator contact makes contact with the base contacts when the actuator is in the closed switch position. The apertures of the actuator and the base provide a generally unobstructed port through the switch in communication with the port of the microphone so that the switch can be disposed over the microphone port in a faceplate of a hearing aid device instead of occupying additional area of the faceplate, thereby saving space within the hearing aid device.
