There is disclosed a switch-hookless telephone set having a housing in the configuration of a handset housing, a cord, a plug and, within the housing, circuitry comprising: a ringing network including a ringing oscillator, a voice network, a receiver, a magnetic transducer performing during voice mode operation of the set as an electroacoustic transducer, and a bistable snap-action OFF-ON switch having an actuating button exposed outside the housing. The switch is coupled to the network and transducer so as, when in a first or "ringing mode" position, to connect the ringing network to, and disconnect the voice network from, the leads in the cord while connecting and disconnecting the transducer to and from, respectively, the ringing oscillator and the voice network, and so as, when in a second or "voice mode" position, to effect the converse connections and disconnections. When the transducer is connected to the ringing oscillator, the transducer is responsive to tone signals therefrom to emit ringing sounds.
