  • Patent number: 9082569
    Abstract: In one embodiment, a system may include an electrical device, an actuator for the electrical device, and an interchangeable frame configured to be removeably attached to the electrical device and to hold the actuator. The frame may be adapted to pivotally engage the electrical device. In another embodiment, an electrical device may have an interface adapted to enable a frame to be attached to and removed from the electrical device, an opening in the electrical device, a subactuator arranged to actuate a switch in the electrical device through the opening, and to engage an actuator on the frame when the frame is attached to the electrical device, and a first rim disposed about the opening. The subactuator may include a second rim arranged to overlap the first rim.
