Abstract
An electromagnetic relay with a return spring is described, where the relay consists of a solenoid coil with a movable armature as the drive and a contact spring assembly, and there is an actuating rod that starts from one end of the armature and engages with spiral springs by means of catches for actuation of the contact, whereby the return spring at the other end of the actuating rod returns the contact spring assembly to home position. In order to achieve a significant reduction in force with the contact spring assembly in actuating the relay, the reset spring here is designed as a top dead center spring such that when the relay is driven against the return spring, the force needed to bend the spring is reduced.
