This is an EMERSON SWQSRR CONTROLLER... p/n 82-0245, 3 way wall controller. Tap on the top of the switch for the light and tap on the bottom for the fan. The sticker on the side reads
"use with SWQ-MOD and SWQAM00 modules only."

120v 60hz 300w max incandescent or haglohen only. Is there a replacement part?
