Abstract

The invention describes a switch, preferably a steering column switch, provided with an actuating member moved across the contact sections rigidly connected to the housing in a substantially pushing way. It is the object of the invention to provide a steering column switch which, being of a small-sized design, permanently provides for good contact making between the contacts to be interconnected. This problem, in the practice of the invention, is solved by ramps raising the contact bridge in the transitory area. Advantageous embodiments refer to the design of the ramp of the conductor bank and of the contact bridge.
