An electrical connector includes a housing having contact channels with electrical contacts received therein each having a poke-in spring beam configured to engage an electrical wire when poked-in to the housing. The electrical contact is movable between a resting position when no wire is present in the wire channel and a clearance position where the electrical contact allows the electrical wire to be removed from the wire channel. Pivot levers are held by the housing and are coupled to corresponding electrical contacts with a pivot end pivotably coupled to the housing and a push button end having a push button pressed to move the corresponding electrical contact to the clearance position. When the electrical wire is loaded into the wire channel, the electrical contact is positioned in a pinching position in which the spring beam pinches against the electrical wire in physical contact with the electrical wire.

Poke-in electrical connector

A Heating, Ventilation, and Air Conditioning (HVAC) controller includes a first cover secured to a second cover, with HVAC components housed by the first cover and the second cover. The first cover may include two or more latches to secure the first cover to the second cover. In some cases, the second cover may include two or more latch receivers each configured to receive one of the two or more latches of the first cover as the first cover and the second cover are brought together. The first and second covers may include one or more guide features. The guide features may be configured to guide movement of the first cover relative to the second cover as the first cover and the second cover are brought together.

A thermostat that is configured to be releasably secured to a wall mountable connector, wherein the wall mountable connector includes a jumper switch that permits an installer or other professional to easily form an electrical connection between different wiring terminals of the wall mountable connector in accordance with how particular field wires are connected to the wiring terminals of the wall mountable connector. The thermostat is further configured to automatically determine the position of the jumper switch of the wall mountable connector, and in some cases, change the control of at least some functionality of the thermostat and/or HVAC equipment depending on the position of the jumper switch.

An adapter plate may be used to secure a wall mountable connector to a junction box by engaging mounting features of the wall mountable connector. In some cases, the wall mountable connector may be directly secured to a wall via fasteners that extend through the same mounting features of the wall mountable connector. In some cases, the adapter plate may be configured such that the wall mountable connector can be secured to the adapter plate simply by pressing the wall mountable connector into position on the adapter plate, where mounting latches of the adapter plate engage the mounting apertures of the wall mountable connector. The wall mountable connector may be an HVAC wall mountable connector that provides an electrical connection between a plurality of field wires of an HVAC system and corresponding terminals of a removably mounted thermostat.

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.

Jumper switch for an HVAC wall mountable connector

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.
