Control device base that attaches to the paddle actuator of a mechanical switch
A remote control device may control electrical loads and/or load control devices of a load control system without accessing electrical wiring. The remote control device may include a control unit and a base for the control unit. The base may include a frame and a mounting tab that attaches to the paddle actuator of a mechanical switch. The mounting tab may be monolithic with the frame. Alternatively, the base may include a resilient attachment member that extends from the frame and is captively retained by the mounting tab. The frame and the attachment member may be configured such that the attachment member is held in a fixed in position by the frame, or such that the attachment member is translatable relative to the frame. The base may include one or more alignment members. The base may cause a rear surface of the frame to be biased against the mechanical switch.
1 . A base configured to be attached to a paddle actuator of an installed mechanical switch that controls whether power is delivered to an electrical load, the base comprising:
a frame that defines an opening that is configured to receive a protruding portion of the paddle actuator, the protruding portion of the paddle actuator projecting outward when the mechanical switch is operated into a position that causes the power to be delivered to the electrical load, wherein, when the protruding portion of the paddle actuator is received in the opening, the frame at least partially surrounds the paddle actuator, and wherein the frame comprises:
an outer wall that extends along a perimeter of the frame;
a cross member that extends between opposed side walls of the outer wall; and
a plurality of mounting teeth that extend from the opposed side walls into the opening, the plurality of mounting teeth configured to be attached to the protruding portion of the paddle actuator,
wherein the plurality of mounting teeth is configured to, when the base is attached to the paddle actuator, engage opposed walls of the protruding portion of the paddle actuator such that a rear surface of the frame is biased against a structure that surrounds the paddle actuator.
2 . The base of claim 1 , wherein the plurality of mounting teeth is configured to secure the frame to the paddle actuator.
3 . The base of claim 1 , wherein each of the plurality of mounting teeth comprises a thin piece of metal that is cantilevered from the frame.
4 . The base of claim 1 , wherein each of the plurality of mounting teeth has a rectangular shape.
5 . The base of claim 1 , wherein the plurality of mounting teeth is evenly spaced along opposed sides of the opening.
6 . The base of claim 1 , wherein each of the plurality of mounting teeth is compliant such that each of the plurality of mounting teeth bends as they engage the paddle actuator.
7 . The base of claim 6 , wherein the plurality of mounting teeth bites into the opposed walls of the protruding portion of the paddle actuator.
8 . A remote control device for use in a load control system, the remote control device configured to be mounted over an installed mechanical switch that controls whether power is delivered to an electrical load, the remote control device comprising:
a frame that defines an opening that is configured to receive a protruding portion of a paddle actuator, the protruding portion of the paddle actuator projecting outward when the mechanical switch is operated into a position that causes the power to be delivered to the electrical load, wherein, when the protruding portion of the paddle actuator is received in the opening, the frame at least partially surrounds the paddle actuator, and wherein the frame comprises:
an outer wall that extends along a perimeter of the frame;
a cross member that extends between opposed side walls of the outer wall; and
a plurality of mounting teeth that extend from the opposed side walls into the opening, the plurality of mounting teeth configured to be attached to the protruding portion of the paddle actuator,
a control unit that is configured to be attached to the frame, the control unit including a control interface and a wireless communication circuit, the control unit configured to translate a user input from the control interface into a control signal that controls a load control device, the control unit further configured to cause the wireless communication circuit to transmit the control signal,
wherein the plurality of mounting teeth is configured to, when the remote control device is mounted over the mechanical switch, engage opposed walls of the protruding portion of the paddle actuator such that a rear surface of the frame is biased against a structure that surrounds the paddle actuator.
9 . The remote control device of claim 8 , wherein the plurality of mounting teeth is configured to secure the frame to the paddle actuator.
10 . The remote control device of claim 8 , wherein each of the plurality of mounting teeth comprises a thin piece of metal that is cantilevered from the frame.
11 . The remote control device of claim 8 , wherein each of the plurality of mounting teeth has a rectangular shape.
12 . The remote control device of claim 8 , wherein the plurality of mounting teeth is evenly spaced along opposed sides of the opening.
13 . The remote control device of claim 8 , wherein each of the plurality of mounting teeth is compliant such that each of the plurality of mounting teeth bends as they engage the paddle actuator.
14 . The remote control device of claim 13 , wherein the plurality of mounting teeth bites into the opposed walls of the protruding portion of the paddle actuator.
