Abstract: A remote drive with a support element for a top-hat-rail mounting. Opposing actuators disposed on the support element alternatingly act on a displaceably mounted slider by rod-shaped anchors. A slider passage receives a first lever arm of a rocker lever pivotable about a rotational axis parallel to the top hat rail length and nearly passes through a rotational point of a shift lever of a switching device. A carrier rail on a second lever arm is parallel to the top hat rail length, the shift lever engaging the carrier rail to the side of the second lever arm. When the slider is displaced, the rocker lever flips simultaneously activate the shift lever.

Alternatively, individually controlled actuators act on first and second legs of a T-shaped rocker switch.

Abstract: The wireless wall thermostat of the present invention utilizes a push-contact mechanical system that allows a user to raise or lower the temperature within a space by applying a force on the top or bottom center of the front of the thermostat. The perpendicular force applied by the user generates a moment arm around pivot connectors, which rotates the thermostat clockwise or counter-clockwise. When rotated clockwise or counter-clockwise, contact buttons attached to the back of the thermostat come into contact with the trigger tabs of a stationary trigger plate mounted to a wall through use of an electromagnetic attraction between a steel disc and a magnet. When the trigger tabs press the contact buttons, the contact buttons send a signal to the central processing unit of the thermostat's internal circuit board to modulate the temperature setting. In addition, the wireless wall thermostat can be detachable by utilizing a magnetic release smart mount.
