Retrofit remote control device

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 base that defines an opening that is configured to receive a protruding portion of a paddle actuator of the mechanical switch therein, the protruding portion of the paddle actuator projecting outward when the mechanical switch is operated into a position that causes power to be delivered to the electrical load, wherein when the protruding portion is received in the opening, the base at least partially surrounds the paddle actuator;
• a control unit that is configured to be attached to the base, the control unit comprising a control interface and a housing, the control unit further configured to transmit a control signal in response to a user input, the housing comprising an upper wall, a lower wall, and opposed side walls, the housing defining a void bounded by the upper wall, the lower wall, and the opposed side walls;
• a battery that is configured to power the control unit;
• and
• a battery holder that is configured to retain the battery therein, the battery holder configured to be installed within the void defined by the housing,
• wherein the battery holder is operable relative to the housing between a first position and a second position such that a location of the battery within the control unit is adjusted, the first position being in a lower portion of the void that is proximate to the lower wall and the second position being in an upper portion of the void that is proximate to the upper wall.
