Abstract: Load-side voltage detection via electric metering processing is disclosed. In one aspect, load-side voltage is provided as an input to a metering processing unit. The metering processing unit determines a voltage level of the load-side voltage. An application processing unit uses the voltage level to control operation of a service disconnect relay.

Abstract: An actuating element for an electric switch, especially for a steering wheel switch in a motor vehicle, impinges upon at least one switching contact and is pivotally mounted on a housing of said switch. A firm hinge is provided as a bearing, connecting the actuating element to a latched wall. The wall runs parallel to the wall of the housing or replaces the wall of the housing.

Abstract: A steering column switch for motor vehicles comprises at least one wiper/washer switch (6 and 31), which is an integral part of a switch lever (1), whereby the contact bridge (16 and 37) of the wiper/washer switch is held in position on a rotary switch member (11 and 32) and acts with several contact arms (18) on switch contact paths (21 and 43) with associate connection contacts (23 and 41). The contact bridge (16 and 37) and the switch contact paths (21 and 41) interact to transfer switch function data in Gray code. This type of coding permits a reduced number of connection lines (25) and connection contacts (23 and 41), compared with the number of switch positions and, at the same time, permits relatively high switching reliability.

Abstract: A steering column switch (1) comprises a carrier (2) with coordinated plug-in fastening (3), which is secured on a holder of the casing tube of the steering column of a motor vehicle, surrounded by a steering column housing, and keys (26, 30, 39) provided with switch elements. On the carrier (2) a plurality of keys (26, 30, 39) acting in different directions of activation are mounted, and these act on contact elements (13, 14) arranged in the carrier (2).
