An electrical switch assembly includes a contact element to be moved towards a further contact element for generating an electrical connection; and a drive for moving the contact element; wherein the drive includes a plunger with a connection member interconnected with the contact element; wherein the plunger includes a mechanical structure with a top side to which the connection member is connection, and a bottom side opposite to the top side; wherein the drive includes a Thomas coil for moving the plunger via an electrically conducting top face, which is provided on the top side and an electrically conducting bottom face, which is provided on the bottom side. The mechanical structure includes at least one channel between the top side and the bottom side, the at least one channel extending transverse to a movement direction of the plunger. Furthermore, the mechanical structure fills less than 50% of a volume between the top side and the bottom side.

The invention relates to an assembly of a gas-tight compartment and an optical voltage sensor that further comprises a module. The module comprises an electro-optic crystal and electrodes, wherein the electro-optic crystal is the only element of the module to mechanically connect the two electrodes and to bridge the potentials of the two electrodes. The assembly is particuarly suited to measure direct current voltages.

A switching device includes a switching element movable from a first position into a second position, a drive unit producing a rotary movement, and a flexible shaft transmitting the rotary movement to the switching element. The shaft has rotatable input and output sections on input- and output-drive sides, respectively. During movement of the shaft, a first rotary angle is producible at the output section, which first rotary angle is less than a second rotary angle at the input section at the same time, such that a first rotary angle shift is produced. The input section is connected to a switching position detection element having a control means with a first region which corresponds to the first position of the switching element and is coupled to the detection element. An identical indication of the detection element can be achieved in case of different rotary angle shifts in the same electrical switching state.
