This NSi Industries EJWT percentage timer switch accepts 120/240 VAC input and its SPDT contacts can activate a 20 amp load or a 2 hp motor. It has 32 repeating cycle time set points that are user-selectable from 15 seconds to 24 hours; only one cycle time can be set. A second dial selects the percentage of time that power is On for the selected cycle; 32 settings for power On from 0 to 100 percent are available. The single-pole double-throw (SPDT) contacts are housed within a plastic enclosure for indoor use that meets NEMA-4X standards for water resistance. This timer switch is Underwriter Laboratories (UL) Listed and Canadian Standards Association (CSA) certified for quality assurance and is suitable for a variety of electrically powered processes, such as livestock feeding or process control.

Time activated switches (also known as timers) operate at preset time intervals during a daily or weekly period and can be either mechanical or electronic. Mechanical timers feature a dial with multiple pins to set the on/off time intervals. Electronic timers feature an LCD display and pushbuttons to set the time intervals. Light activated switches (also known as optical or photo) operate when ambient light levels reach preset values, generally measured in foot candles. Motion-activated switches (also known as motion sensors) operate when an electronic field of a preset range is interrupted. These switches can include energy saving logic that uses combinations of time, light, and motion to operate and can include one or more device outlets or circuit contacts. Automatic switches are used to control indoor lights, outdoor lights, appliances, and small equipment motors.
NSi Industries manufactures electrical components and sensors, lighting products, and energy management products. The company, founded in 1975, is headquartered in Huntersville, NC.

Using to milk a low output deep well into a water storage tank. Set for 5% at 2.5 hours (7.5 minutes out of 150 minutes). For my situation this pumps about 40 gallons every 2.5 hours. Output from this Tork timer switch runs through my float switch, if the float is down during the Tork RUN signal the float switch passes the signal through to a contactor to run the submersible pump in the well, if the float is up the tank is obviously full and the Tork RUN signal doesn’t make it past the float switch. Even though I run a lot of wiring, I had to call Tork to clarify their electrical drawing for my 120V application. They were very helpful and my question was resolved in less than 2 minutes. As of 2021 this has been operating 24/7 for >2 years with no attention.*UPDATE- 4 years in as of February 2023 and very happy, no issues whatsoever. An added benefit for submersible wells is that this prevents ‘short cycling’ where the well motor doesn’t run long enough to cool down properly if feeding a small pressure tank, and obviously it also dramatically reduces the number of cycles the well pump motor is asked to run each day.

The timer works perfectly for my application. I have a well pump that needed to be turned on every 30 minutes and run for 1 minute. the percentage and time were right on.The instructions are not accurate for hook up. My application was 240 vac. It requires a jumper. If it if wired as the instructions say is will not cycle. I had to do a lot of searching for a picture of where someone had got it wired correctly.

This is perfect for our application; a well that needs to fill a cistern by running 4 minutes out of each hour. However, we tried to run the timer side of the circuit using 208 instead of 1 hot leg and a neutral to give it 120. It looked like it was functional on the 208, but it couldn't close the relay. Once we pigtailed over a neutral, it works perfectly. I really wish the instructions had specifically noted that 208 wouldn't work - it would have saved us some time. I would definitely buy it again.EDIT: It's now a few years later, and this unit failed leaving us with no water and a fear that our well pump had failed. After we cut it out of the circuit, the well pump runs. We're looking for a replacement, and we may try to pull the relays off the board. Seems like the relays on the board might have failed.

Works great! Wiring up was trickier than you would expect. I always thought common and neutral where one of the same….not so. With the 110v setup, had to run a shared hot (jumper) to the “commonâ€

I dont understand how this thing works cant find a video that explains in detail how its set up or how it reads. Don't see any sensors... or outlets for my humidifier. Confusing

Worth the extra money, don't buy the cheapest one you can find if you need reliability

Amazon said I have to reach out to the seller so here I am please contact me.So I got the switch for my Shiitake farm. had it set to 2 mins at 25% so I can have an RH of 85%, worked fine for about 2 months now. it will not turn off and the light shows red for being off but it is still having power sent thourgh to my mister and it just stays on. I've unplugged it, and opened up the box to see this white powdery stuff all over the wires and on the housing. I was expecting something black and burnt.
