ABSTRACT:
A transfer switch for differential type actuators which includes a body having an internal space, a plurality of pairs of output ports connected with the internal space for supplying pressure to a plurality of differential type actuators, a flat control plate rotatable on the output ports, passages of two routes being arranged on one surface of the control plate which are connectable selectively with the plurality of output ports, input ports connected with the individual passes, and a rotary mechanism for changing over selectively the position of the control plate, whereby the function of the differential type actuator can be exerted fully and a plurality of differential type actuators can be controlled selectively and reliably.
