Intermatic 2-Hour Spring Wound Timer
This in-wall time switch uses a mechanical spring-wound mechanism to provide up to two hours of timed control. It is designed for installers and facility managers who need a simple, power-free delay for lighting or motor loads. The single-pole single-throw action opens or closes one circuit when the set time expires. No external power source is required for the timing function.
SPST 120/240/277V Wiring and Load Handling
The timer carries a 7/10/20A rating and supports 1HP motor loads across 120, 240 and 277V supplies at 50/60 Hz. It fits standard in-wall boxes and frees the installer from running a separate control transformer or electronic timer supply. Builders who need multi-circuit control or programmable daily schedules cannot use this single-circuit mechanical unit.
