Abstract
The relay has a magnet system with an armature that operates on a switching spring via an actuating element. This switching spring has a frame-shaped contact spring as well as a fork-shaped reset spring, intermeshed in one plane and mutually decoupled, whereby the reset spring guides the actuating element via at least two linkage points lying in a line parallel to the pivot axis. The relay of the present invention provides a compact construction with few individual parts and a very low-friction operation.
