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.

Abstract: A compact laser machining head is used for laser machining of material, in particular for laser-supported material machining methods for 2D and 3d laser machining. This laser machining head includes a sensor for geometry recognition and/or following contours, one or a plurality of mirrors and/or mirror systems with a mirror housing and mirror holder, a defined interface with the beam guidance system of the machine, and further required structural elements, connections and lines. In this compact laser machining head, the sensor is structurally completely integrated into the laser machining head, is seated, together with other auxiliary devices of the laser machining head tied to the working direction, rotatable around the rotary shaft of the sensor.
