PURPOSE: To finish one switch with one time of switching operation by providing a second actuator which controls the operation of a first actuator on the basis of output from a delay time control means.
CONSTITUTION: When a moving armature 10a of a switch 10 is tilted to the side of a fixed contact 10c, a high level signal is fed to a control circuit 12 via an input interface circuit 11. With this constitution, this control circuit 12 makes a terminal 12a into a high level from the low level, and in a motor 7, a current is fed in an A direction by a first drive circuit 15 and a door is thus locked. In addition, a high level signal out of this control circuit 12 is made to feed the current to a motor 18 in a C direction via a second time constant circuit 14, operating a crossbar mechanism to a door locking mechanism.
