Abstract
An improved supply circuit for electromagnets. The supply circuit comprises a bridge rectifier, an attracting winding positioned in the diagonal of the bridge rectifier, a holding winding placed on the magnetic circuit of the electromagnet, and an isolating contact which isolates the bridge at the end of the pulling-in course of the movable member of the magnetic circuit. The holding winding being connected in parallel across the system formed by the isolating contact and the bridge rectifier.
