ABSTRACT:
A multiple switch, particularly for a motor vehicle, has a switch base, an input fixed contact arranged on the switch base, a plurality of output fixed contacts which can be connected with the input fixed contact, a ramp, contact bridges controlled by the ramp and bringing the output fixed contacts in contact with the input fixed contact, a driver movable relative to the switch base and individually supporting and guiding the bridges, springs providing a required contact pressure between the contact bridges and the input fixed contact and the contact bridges and the output fixed contacts. Each of the contact bridges have axle which is freely rotatable relative to the driver and carries a contact roller. Each of the contact bridges or the contact roller is provided with a control part which comes into contact with the ramp has a peripheral surface which produces a rubbing friction for turning the contact bridge or the contact roller about its longitudinal axis.
