Electromechanical appliance timers provide valuable functionality by reliably automating an outlet, allowing home or business owners to program their lights or heavy-duty appliances to match their schedule. The TU40 features a water-resistant enclosure to protect the multi-volt timer mechanism from outdoor usage, making this timer the perfect choice for air conditioners, water heaters, pumps, signs, fans, or landscape/holiday lights. The captive tab system allows the user to program multiple ON/OFF times in 15-minute increments over a 24-hour schedule. Set the timer using the ON/AUTO/OFF switch, or put it into vacation mode to provide home security by turning lights on and off while you're away. For more involved wiring usage, the TU40 features 4-in-1 DPDT contacts to include SPST, SPDT and DPST. Trust in the reliable timing of TORK, a pioneer in the electrical industry since 1922.
