Abstract
The rotating armature relay exhibits one or two ferromagnetic bars which are provided with an insulating covering in their central area. Contact springs are secured in the insulation covering, the contacting, free ends of said contact springs respectively interacting with cooperating contact elements anchored in a base body. As a result, a slide-free and, thus, low-friction actuation derives as, however, does relatively high friction at the contact locations, whereby contact impacts are suppressed and foreign layers are abraded from the contact surfaces.
