  • Two-wire dimmer switch for controlling low-power loads
    Patent number: 8963440
    Abstract: A two-wire load control device such as a dimmer switch for controlling the amount of power delivered from an AC power source to an electrical load such as a high-efficiency lighting load may be provided. The load control device may include a bidirectional semiconductor switch coupled between the source and the load and a controller operable to control the bidirectional semiconductor switch. The load control device may also include a front accessible trimming actuator to adjust a low end intensity setting of the load control device. The trimming actuator may be coupled to the controller such that the controller may control the bidirectional semiconductor switch appropriately. Additionally, the trimming actuator may include indicia to help a user readily identify the proper low end intensity setting.
