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.
