Abstract
An electromagnetic clutch includes a mechanism which is responsive to a first short energization of an electromagnet thereof to cause a spring arrangement therein to snap to a reverse configuration wherein it holds the clutch engaged until a second short energization with a current larger than that used for the first energization, whereupon the mechanism again reverses the configuration of the spring and subsequently causes the clutch to disengage.
