Abstract: Electronic devices are provided with housings that can have smoother profiles and with switch assembly input components with knobs that can move along tracks in directions at least partially offset from the directions of anticipated resistive forces. The housings can include switch assembly input components with knobs that may move along linear tracks and switch assembly input components with knobs that may move along curved tracks.

Abstract: A control device includes a sensor, an analysis unit, and a control unit. The sensor includes a stationary member and a rotatable member. The stationary member includes a first electrode and at least two second electrodes. The rotatable member includes a third electrode and a fourth electrode. The first electrode electrically contacts the third electrode and each second electrode electrically contacts the fourth electrode in sequence when the stationary member is rotated. The analysis unit is configured for determining which second electrode electrically contacts the fourth electrode. The control unit is configured for executing a corresponding command based upon the determination of the analysis unit.

Abstract: The present invention provides a rotary manipulation type electronic device which permits one to obtain a feel of manipulations during rotational manipulations and produces lilting sounds of manipulations to thereby obtain an audiological sense of manipulations. The rotary manipulation type electronic device of the present invention has a base body with which a rotary body is rotatably combined. An operative element is disposed in such a way that movement of the operative element is restricted by the inside wall of a terminal leading portion of the base body and by leg portions of a leaf spring. Engagement portions engaging an uneven portion of the top surface of a flange portion of the rotary body protrude from the operative element. The leaf spring is brought into elastic contact with the top surface of the operative element.

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 device and method is described for safely recognizing a switch position angle of a rotary switch. Two redundantly configured computer units are provided to determine discrete switch positions of the rotary switch by evaluating two actual analog switch position signal values corresponding to the switch position angle, with each computer unit separately checking the actual analog switch position signal values for plausibility. Faulty switch position angles are identified by comparing the switch position angles determined by the first and the second computer unit.

Abstract: A transfer switch assembly to alternatively connect an electrical load to a primary or to a secondary power source. The transfer switch uses two conventional switches, or circuit breakers, having pivot type or linear type actuating members. A conventional linear motor is used. The actuating members of the switches, or circuit breakers, are in contact with the movable portion of the linear motor through a coupling mecanism. The coupling mecanism ensures that the switches, or circuit breakers, are not in a closed position simultaneously.

Abstract: A location marker includes a casing, a switch assembly and a lens enclosing a flashable strobe lamp. The location marker is powered by batteries and an electronic circuit that converts the battery voltage to a trigger voltage for illumination of the strobe lamp. The switch assembly is non-intrusive and maintains water tight integrity inside the casing. The switch assembly futher includes a magnetically operable switch for selectively connecting and disconnecting two pairs of terminals. An R.F. transmitting location marker is also employed using a transmitter circuit and an antenna.
