摘要：
A circuit for controlling a camera or a motor drive device by means of a control switch unit connected through a pair of connecting terminals thereof to a pair of remote control terminals of said camera or motor drive device, wherein the control switch unit comprises plural control switches and a voltage generating circuit adapted for generating plural different voltages in response to various combinations of the states of said control switches; and said camera or motor drive device comprises plural voltage detecting circuits of different detecting voltages for detecting the voltages supplied to the remote control terminals. The camera or motor drive device is controlled in response to the outputs from said voltage detecting circuits.
