The electrical turn/pull switch for vehicle lighting has an operating part ( ) that is mounted in a switch housing ( ) so as to be rotatable as well as axially movable. The movable contact elements ( ) of a contact carrier ( ) interact with fixed contact elements ( ). The contact elements for the turn switch function ( ) and for the axial switch function ( ) are integrated on the contact carrier ( ). An actuation part ( ) entrained by the operating part ( ) has cams and/or ramps ( ) that engage the movable contact elements ( ) and actuate them.

Electrical switch for vehicle lighting

An electric switch has a switch housing, a knob mounted in the housing, a guide gate having latching recesses and arranged inside the switch housing, and a spring-loaded cam follower guided by the guide gate. The switching positions of the switch are defined by interaction of the cam follower with the guide gate and with its latching recesses. The guide gate has damping elements made of elastic material and fitted in the latching recesses.

Electric switch with damping elements to minimize switching noise

A fuse box for motor vehicles includes a housing that is adapted to contain electrical fuses mounted to a common busbar for connecting one end of the fuses directly to a pole of an electric battery in the vehicle. The housing includes lateral surfaces for providing torsional protection to the fuses against twisting or bending when the nuts holding the fuses in place are tightened. Screening zones are defined in the housing for screening off fusable portions of the fuses so that melted material is prevented from migrating into the housing beyond the screening zone where the melted material may cause damage. Mechanical coding structures are provided in the housing to ensure that only cable terminals having a shape corresponding to the coding structures can be installed in selected regions of the fuse box. This prevents inadvertent misuse of cross-connection of cables having inadequate or excessive current carrying capacity. A removable intermediary bottom member carries the lateral surfaces, screening zones and other mechanical coding structures so that the subject fuse box can be easily reconfigured.
