A wall mountable connector for securing a thermostat to a wall is disclosed. The wall mountable connector may include built in jumper functionality. In some cases, the wall mountable connector may include a plurality of wiring terminals as well as structure enabling an installer or other person to easily electrically connect (e.g. jumper) one or more of the wiring terminals in order to accommodate different equipment installations. For example, in some cases there may be a desire to electrically connect (e.g. jumper) or disconnect certain wiring terminals that correspond to transformer input terminals, which in some equipment installations are intended to be independently powered while in others they are not.

A wall mountable connector for securing a thermostat to a wall may include a plurality of wiring terminals as well as structure enabling an installer or other person to easily electrically connect (e.g. jumper) two or more of the wiring terminals in order to accommodate different equipment installations. For example, in some cases there may be a desire to electrically connect (e.g. jumper) or disconnect certain wiring terminals that correspond to transformer input terminals, which in some equipment installations are intended to be independently powered while in others they are not. In some cases, the wall mountable connector may include a slider with a cam that selectively lifts a conductor to disconnect two or more wiring terminals. The wall mountable connector may also include structure that helps prevent electrically connecting field wires to particular wiring terminals in error, depending on the position of the slider.

Implementations of a modular electronic switch system are provided. An example modular electronic switch system can be attached to a mounting interface for firearm accessories, such as a Picatinny rail interface, and used to operate power-consuming firearm accessories (e.g., an illumination device, a laser aiming module, etc.) connected thereto by a suitably configured flexible cable, or wireless transceiver. Also provided are implementations of a remote switch device. An example remote switch device can be attached to a mounting interface for firearm accessories and used to operate power-consuming firearm accessories connected thereto by a suitably configured flexible cable. The remote switch device includes at least one non-binary position and force sensor.
