Abstract:
A microphone with and exterior, comprising:a housing; a terminal member disposed in said housing and including a plurality of spaced apart terminals; and a variable resistance switch including at least an elongated resistance member disposed in said housing, extending in a longitudinal direction, and having opposite first and second ends connected to respective ones of said terminals, an elongated conductive member disposed in said housing adjacent and parallel to said resistance member, and having one end connected to a respective one of said terminals, and a slide member including at least a resilient conductive wiper that is disposed in said housing and that is simultaneously and constantly in sliding contact with said resistance member and said conductive member so as to complete a circuit through said terminals, said conductive member, and said resistance member, said slide member being operable to move in said longitudinal direction between an ON position, in which, said wiper is in sliding contact with said second end of said resistance member, and an OFF position, in which, said wiper is in sliding contact with said first end of said resistance member, said wiper being slidable over said conductive member and said resistance member so as to linearly vary the resistance in said circuit when said slide member moves between said ON and OFF positions.
