Abstract: An electrical switching device, in particular a circuit breaker, is disclosed. In order to shorten the opening times of a switching device such as this, a snap-action system is used. The system interacts with the moving contact piece, of an electrical switching device having a switching shaft and having a moving contact piece which can be operated by the switching shaft, such that the moving contact piece is automatically moved to a switched-off position after opening of the contact by electrodynamic forces in the event of a short circuit or the like. The contact load on the moving contact piece decreases as the opening increases. This may result in better short-circuit current limiting. The overall production costs may be considerably reduced.

Abstract: A wireless device to be mounted on a license plate of an automobile is composed of a casing, components contained in the casing and an operating member inserted into the casing. A battery for supplying power to the components is selectively turned on or off by controlling an insertion depth of the operating member into the casing. At an initial depth, the power supply is turned on for testing the wireless device at a manufacturing plant. At an intermediate depth, the power supply is turned off to save energy consumption in periods of transportation or storage. At a final depth, the power supply is finally turned on for actual use of the wireless device, and the casing is hermetically closed by the operating member.
