Instantaneous switch

The invention relates to an instantaneous switch for control circuits of electrical systems. The object of the invention is to overcome the disadvantages of known instantaneous switches and to provide an instantaneous switch with a simple design and a reliable action. This object is achieved according to the invention in that supports which are fixedly connected to the baseplate are constructed above the levers of the known switch, having a cylindrical helical spring between the sliding element and the ends of the contact link and at a specific distance from the same. One version of these supports expediently has projections of the baseplate parts. A further possible version of these supports consists of their its construction as connecting elements of both baseplate parts. The advantages of the instantaneous switch according to the invention are its simple design, reliable operation and increased vibration resistance.
