Spring-wound timers provide simple manual countdown control for equipment that should run only for a limited period. The Intermatic DPST Spring Wound Timer [60 Min] [20A] (FF460M) is a double-pole single-throw timer designed for compatible 60-minute control applications rated up to 20 amps. This timer is commonly used where users need a mechanical countdown control for pumps, blowers, lights, heaters, or accessory equipment without relying on a digital controller. Replacing a worn timer restores predictable shutoff, helps prevent equipment from being left on too long, and provides a familiar manual control point. 60-minute spring-wound countdown timer DPST switching configuration 20A rating reference Useful for pumps, blowers, lights, or accessories Helps provide automatic shutoff after manual activation
