Title:
CONTROL CIRCUIT FOR SWITCH DEVICE, AND SWITCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/159041
Kind Code:
A1
Abstract:
Provided is a control circuit for causing a movable contact point in a switch device to return at a high-speed compared to prior art. This switch device contains a first switch element having a movable contact point, and a drive coil for controlling the movable contact point of the first switch element. When a power source voltage is supplied from a power source, the drive coil turns-on the movable contact point, and then, a control circuit for the switch device causes the movable contact point to return when the supply is turned-off. In the control circuit, a rectifying circuit or a surge absorbing element is connected between the power source and the control circuit. The control circuit further comprises, inserted between the first switch element and the rectifying circuit or the surge absorbing element, a second switch element that is turned-off when the supply of the power source voltage is turned-off. The control circuit turns-off the second switch element, thereby turning-off the first switch element.
