Abstract (en)
The present invention is a kind of switch device for the control of two or above two electromagnetic actuator, for driving coil such as electromagnetic brake, electromagnetic clutch, electromagnetic switch, electromagnetic relay, and electromagnetic valve, etc. to perform parallel actuation, so as to generate better electromagnetic actuation power, and through the control of switch device, take driving coil switch into serial connection state to reduce the electrical current of driving coil, but still maintain the operation of electrical actuation in order to save electricity and reduce the heat generated by electromagnetic actuator.
