Abstract

The invention relates to an electrical switch, in particular for a motor vehicle. The switch has a housing in which a contact system is located. Electrical connections which are located on the housing lead to the contact system, of which electrical connections first electrical connections are used to apply a power voltage for a high power current, and second electrical connections are used to apply a signal voltage for a low signal current. Optionally and if required, one connection can carry the power current via the first electrical connections and/or the signal current via the second electrical connections. Electrical switches designed in such a way are particularly suitable for arrangement in a control panel for a motor vehicle.

Claims15

Dependent claims

An electrical switch comprising:

a first contact system comprising at least one fixed contact and one switching contact, the first contact system being designed for switching a high power current as well as a low signal current;
and
a plurality of electrical connections which lead to the first contact system, wherein the electrical connections comprise first electrical connections for application of a first voltage in the form of a power voltage for a high power current, and second electrical connections for application of a second voltage in the form of a signal voltage for a low signal current, the first electrical connections and the second electrical connections being electrically connected to only the one first contact system, in that, one connection can carry at least one of the power current via the first electrical connections and the signal current via the second electrical connections to the contact system.

Dependencies are inferred from the claim text.
