There is provided a rail attachment apparatus for an electrical device in which a biasing elastic function is imparted to a slider itself, whereby the slider can be adjusted to be thin and the number of components can be decreased. The rail attachment apparatus includes a nipping portion that nips one side edge of an attaching rail fixed to an attaching surface of the electrical device, and a slider that is opposed to the nipping portion and slidably held at the other side edge of the attaching rail in a direction intersecting with this attaching rail. The slider is provided with integrally formed bending elastic portions which bias the slider in a direction to enable nipping the attaching rail.

An electrical distribution block includes a first base, a second base, and a spacer plate discrete from the first and second base. The spacer plate is positioned between first base and the second base and secures the first base to the second base. A conductor block is connected to at least one of the first base or the second base. The conductor block includes a primary tap and a secondary tap.

A building controller may include a housing having a back plate and a mounting clip, which may be slidably disposed relative to the back plate between a wall mount position used when mounting the building controller to the wall, and a DIN rail mount position used when mounting the building controller to a DIN rail. When in the wall mount position, the mounting clip and the back plate may be configured to hold the mounting clip in the wall mount position until at least a first threshold sliding force is applied to the mounting clip. When in the DIN rail mount position, the mounting clip and the back plate are configured to hold the mounting clip in the DIN rail mount position until at least a second threshold sliding force is applied to the mounting clip.

The spacer plate is positioned between first base and the second base and secures the first base to the second base. A conductor block is connected to at least one of the first base or the second base. The conductor block includes a primary tap and a secondary tap.

A retention mechanism for attaching equipment to a mounting rail comprises a slider including a first retention section and a pivoting lever mechanical coupled to the slider. The slider is movable in a translational manner along a sliding direction with respect to a remaining portion of the retention mechanism. The lever includes a second retention section aligned with the first retention section in the sliding direction. A reception area for receiving the mounting rail is defined between the first retention section and the second retention section.

A railway termination shunt enclosure including one or more receptacles, each of the one or more receptacles being configured to receive a termination shunt. The enclosure also includes at least one mounting surface and a connector assembly rotatably attaching the one or more receptacles to one or more of the at least one mounting surface.

A building controller may include a housing having a back plate and a mounting clip, which may be slidably disposed relative to the back plate between a wall mount position used when mounting the building controller to the wall, and a DIN rail mount position used when mounting the building controller to a DIN rail. When in the wall mount position, the mounting clip and the back plate may be configured to hold the mounting clip in the wall mount position until at least a first threshold sliding force is applied to the mounting clip. When in the DIN rail mount position, the mounting clip and the back plate are configured to hold the mounting clip in the DIN rail mount position until at least a second threshold sliding force is applied to the mounting clip.

An assembly includes a mounting bracket; a member; a guide disposed in the member; and a slider, the slider configured to move between a first position and a second position relative to the member, the slider being configured to move within the guide. The slider has a first end and a second end, the first end opposite the second end. The first end includes a first portion and a second portion, the first portion configured to provide a contact for application of a force in a first direction and the second portion configured to provide a contact for application of a force in a second direction. The second direction is opposite the first direction.

A circuit interrupter adapted to be detachably connected to a rail system includes a housing having a notch disposed thereon adapted to receive a first leg of the rail system. An engagement member having a notch disposed therein adapted to receive a second leg of the rail system is slideably carried by the housing such that the notch in the engagement member is moveable in a first plane toward and away from the notch in the housing between an engaged position and a disengaged position. An actuation member is slideably carried by the housing and is moveable in a second plane, different than the first plane, between an actuated position and an unactuated position, movement of the actuation member in the second plane being translated into movement of the engagement member in the first plane.
