Abstract
Abstract The invention relates to a combined dictation machine and detachable microphone cradle. The bottom of the dictation machine has a pair of sockets, one being electrically connected to the power circuit and the other being closed by a leaf switch element completing the circuit. The microphone cradle includes a pair of projecting pins connected to a microphone-operated normally closed switch. Upon insertion of the pins of the microphone cradle into the sockets of the dictation machine the leaf switch breaks the power circuit within the dictation machine and completes the circuit through the normally closed switch in the cradle so that control over the power circuit of the dictation machine is transferred to the microphone-operated cradle switch.
