Mechanical Timer Switch 15A
This 24-hour in-wall mechanical timer switch controls lights, fans and other indoor loads on a repeating daily schedule. It mounts in a standard electrical box and requires a neutral wire for operation. The unit is ETL listed and rated for 125 VAC circuits.
Dimensions and Wiring Needs
The timer body measures 4.65 inch height by 2.87 inch width, which is larger than standard devices and will not fit typical wall plates. Installation requires a compatible cover plate and a neutral conductor in the box. The mechanical dial with 30-minute interval tabs sets on and off periods without batteries or programming menus.
Load Compatibility and Limits
Suited for homeowners automating lamps, ceiling fans or holiday lighting on a fixed daily pattern. It handles 15 A general or resistive loads, 1250 W tungsten, ½ HP motor and 500 VA electronic ballast. Not suited for loads exceeding these ratings, for circuits without a neutral wire, or for installations needing a standard-size wall plate.
