Patent number: 11863061Abstract: A switch includes a first terminal, a second terminal, and a third terminal. The switch includes an output node coupled to the second terminal and the third terminal. The switch includes a contactor coupled to the first terminal and movable between at least a first position and a second position. The first terminal is coupled to the second terminal when the contactor is in the first position. The first terminal is coupled to the third terminal when the contactor is in the second position. When the contactor is in the first position, the switch is configured to provide direct current power at the output node. When the contactor is in the second position, the switch is configured to provide alternating current power at the output node.Type: GrantFiled: May 23, 2022Date of Patent: January 2, 2024Assignee: Progress Lighting, LLCInventors: Thomas Warren Weeks, Jr., Douglas Matthew Hamilton
