The present invention is directed to an electrical wiring system having a frame assembly that includes a frame opening at a central portion thereof. The frame opening provides access to the interior of the device wall box. At least one electrical wiring device is configured to snap into the frame opening such that the interior of the device wall box is completely enclosed by the frame assembly and the at least one electrical wiring device such that access to wiring disposed within the device wall box is substantially prevented. The at least one electrical wiring device includes at least one user-interface. An aesthetic overlay may be coupled to the frame assembly. The aesthetic overlay includes an overlay opening configured to accommodate the at least one user-interface such that the at least one user-interface is accessible to a user.

A transmitter device incorporating a strain gauge proportional push button is disclosed. The transmitter device includes a printed circuit board including one or more electrical components thereon and a proportional push button having a flexible membrane, a dome switch positioned beneath the flexible membrane and attached to the printed circuit board, the dome switch being proximate to the flexible membrane such that depression of the flexible membrane causes the dome switch to snap down and thereby form a closed circuit in the dome switch, and a strain gauge formed on or applied to the printed circuit board and positioned adjacent the dome switch, the strain gauge generating an electrical output proportional to an amount of deflection of the printed circuit board caused by pressure exerted thereon by depression of the flexible membrane and the dome switch.

A snap-action switching element with normally closed contact comprises includes a contact arm movable between a rest position and a switching position, and an actuating member with which the contact arm can be moved between these positions. A rocker switch is arranged at one end so as to be rotatable and a tension spring is suspended at the other end of the rocker switch on a spring suspension section. The actuating member has a rocker bearing opening which is provided transversely to its direction of movement and into which engages a rocker bearing actuating section provided transversely to a main plane of the switching rocker. In the case of a normally open contact, the first contact point is then arranged at a distance.

A wireless switch includes a cover member, a button member, a first plunger, a second plunger, a trigger spring, a return spring, a shaft, a housing, and a power generation module. An intermediate member constituted of the first plunger, the second plunger, the trigger spring, the return spring, and the shaft is connected between the button member and the power generation module. The intermediate member prevents a position of the shaft making contact with the power generating shaft of the power generation module from changing, and causes stress to build up in the trigger spring, until a movement distance of the button member reaches a predetermined distance. The intermediate member releases the stress built up in the trigger spring and pushes the power generation shaft with the shaft using the released stress upon the movement distance of the button member reaching the predetermined distance.

A wireless switch includes a button member, a power generation module, an RF module, and a notification unit. The button member is mounted in a housing, and is configured to move. The power generation module is configured to generate power using energy produced by the movement of the button member. The RF module is connected to the power generation module, and is configured to transmit a switch signal using power generated by the power generation module. The notification unit is configured to operate using power generated by the power generation module. The RF module controls the notification unit in one or more notification states according to a strength or details of a reception state signal corresponding to the transmitted switch signal.

The present invention is directed to a method including the steps of providing a frame member configured to be disposed over a device wall box, the frame member including at least one frame opening having a lip member configured to substantially extend into an interior region of the device wall box, the at least one frame opening being further configured to substantially define a modular space; and providing at least one modular electrical wiring device configured to substantially conform to the modular space in accordance with at least one of a plurality of modular configurations, the at least one modular electrical wiring device being configured to include a plurality of attachment structures configured to mate with the frame member, the at least one modular electrical wiring device being configured to be disposed within the at least one frame opening in an orientation selected from a plurality of orientations including at least one first orientation and at least one second orientation, the at least one first orientation being substantially orthogonal to the at least one second orientation.

The present invention is directed to switch device disposed in a housing with a back body portion, the device includes a switch actuator having a user-accessible surface, the user accessible surface includes an indicator element and an interior channel optically coupled to the indicator element. A light emitting portion is disposed within the interior channel and optically coupled to the indicator element so that the interior channel moves relative to the light emitting portion when the switch actuator moves between the first actuator position and the second actuator position. The light emitting portion is optically coupled to the indicator element when the interior channel moves relative to the lighting portion. A modular lighting assembly is removably coupled to the back body portion at a fixed position so that a light emitting portion of the modular lighting assembly is disposed within the interior channel and optically coupled to the indicator element.
