I kept leaving my pool cleaner booster pump on for hours when it only needed 20 minutes at a time. Now I can give it a quick turn and not worry about it.Works great.For years, I've been manually starting and stopping my underground water pump. Finally found this switch on Amazon. Now I can start the pump manually and automatically stop the pump at the time interval set on the switch.Yay, I looked all over for this, a special DPST version of the regular windup timer. It's working great.Like all mechanical timers, you have to pull out the mechanics and douce it with light oil. I used 3-in-one (one time) and timer gets plenty of daily use for over a year.Using these on my outdoor patio heater. Instal was easy and they work great. Best value for my higher wattage application.Only timer I could find at this voltage. But not very stylish, does not sit well in the junction box (recessed, not flush with plate).I needed a timer for my new 240V 2000W Cadet heater. This fit the bill. Easy to install with basic electrical knowledge.simple, works. does make a very subtle ticking sound which does not bother me
