Abstract: There is disclosed structure which overcomes the deficiencies with respect to prior art devices by providing a wiring device such as a switch having a paddle that pivots about its upper end and is biased to assume the same at rest position when either in its on position or off position. Repeated pressing and releasing the lower portion of the face of the switch paddle alternately closes and opens a set of contacts within the switch to alternately connect and disconnect a load form a source of electricity each time the paddle is pressed. Thus, regardless of whether adjacent switches are on-off switches or 3-way switches, they will always be in alignment. An on-off indicator such as a small light is provided to indicate to a user when the contacts of the switch are opened or closed. The paddle of the switch has a length-width ratio dimension that is proportioned to provide a finger contact surface of increased area to allow a user to more easily and quickly identify and operate a particular switch.

The control module includes a housing in-line with and directly attached to the circuit breaker inside the panelboard and a pair of contacts coupled to an actuator mounted in the housing. One contact is coupled to the load lug and one contact is coupled to the load wire. The actuator is operated from a location remote from the control module and the contacts operate independently from the circuit breaker.

Abstract: A keypad assembly includes a pressing surface layer, a pattern layer, an elastic layer, a light guiding layer, and a pressing bottom layer. The pattern layer is under the pressing surface layer. The elastic layer is located between and interlocks the pattern layer and the light guiding layer by adhesive. The pressing bottom layer adheres to the light guiding layer. The keypad assembly has an ideal appearance by lights collection of the light guiding layer. User can feel comfortable when pressing the keypad assembly because of the elastic layer's buffering effect.

Abstract: In a pressure switch with a housing in which a plunger element is located that is movable against a spring force of a first elastic element—contacts being located directly or indirectly on the plunger element, and the first elastic element being located on the side of the plunger element facing toward or away from the media connection—a second elastic element is provided, against the spring force of which the plunger element can be moved. As a result, the pressure switch can be used for pressures>200 bar in situations where overall dimensions are small.

Abstract: Pedal assemblies and methods provide for signal control, such as for controlling audio and/or effects path signals used in generating audio from a musical instrument. The pedal assemblies may provide for simultaneous audio and effects control via electrical pathways dedicated to each. Rotation of the pedal about one or more axes of rotation results in modifying an electrical characteristic of devices of the pedal that control the audio and effects path signals. A particular axis of rotation that modifies the electrical characteristic of a device may be configured to produce a particular audio or effects path control based on which of the jacks are in use such that by changing the jacks that are in use, the function of a particular axis of rotation may change. Furthermore, a pedal assembly may provide for two axes of rotation where the centers of rotation of the two axes are non-coincident. The two axes of rotation may be better isolated as a result.

Abstract: A touch sensor device for a household appliance or the like is disclosed, for producing a signal for controlling the appliance's operation when touched by a user's finger. The sensor comprises a capacitance sensor element connected to control circuitry, wherein the sensor is connected to a first side of a circuit board, typically facing towards the inside of the appliance. In the same vicinity on the other side of the circuit board is a conductive field that is not galvanically connected to the sensor element, but which is positioned against a non-conductive panel, the other side of which forms the exterior of the appliance. The exterior surface of the panel is a touch area, so that contact by a user's finger in the touch area alters the capacitance, which is detected by the capacitance sensor element and is detected by the control circuitry for controlling the appliance.

Abstract: An electrical switch may comprise a base having three electrical conductors thereon and an electrically conductive flexible dome adjacent the base. The flexible dome has plural longer legs extending from its dome and in electrical contact with a first conductor, has a shorter leg extending from its dome and overlying a second conductor, and has its dome overlying a third conductor. A pushbutton must be moved over a distance substantially greater than an actuation distance of the flexible dome to apply sufficient force to cause the shorter leg to contact the second conductor and the dome to contact the third conductor. A spring between the pushbutton and the flexible dome couples force to the flexible dome.
