DO NOT BUY! - Kept getting hung up and lights would stay on all day...finally clock face has fallen off. DO NOT BUY Review: Works - I have had this unit installed for less than a week, and it is working. I have it connected to a hot water heater, it activates at 1800 hours and turns back off at 2200, and so far the unit has done what it appears to do. I like to think i know a thing or two about anything electrical, however i would not have known what L1 and L2 meant when wiring anything 220 volt. i spoke with a licensed electrician about two weeks ago and he reference thins so I knew what it meant when i went to wire up the device. There is a spot on the timer for a ground however the neutral does not have anywhere to connect it to. This simply means to put a splicer and make it bypass the timer all together. have had no issues working the timer.

Spa’s are 50 amps. This time clock only goes to 40 amps **Q: How do you mount a Tork 1109 timer to a wall?** A: Its not designed to be installed in a wall. The cover won't open. You could cut a hole in the wall next to a support and mount it that way . Use a finish cover to conceal it. **Q: Is this time a single pole single throw or is it is 2 pole single throw?** A: Single pole, single throw I believe. There are much better options than this unit. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Junk never worked properly.

Great buy for the money ### ⭐ Terrible Design - Would not recommend *by J***. on September 21, 2020* Update to an earlier review. While this seems to be a good quality product it does not hold up for even a few months. I installed this at the end of last summer for my pool pump. It started having problems turning the switch off after only a few weeks. Now it is not working at all. The clock keeps time and turns the pump on, but it always gets stuck turning the switch off. The mechanism is so difficult to operate that the off tripper will bend and go past the off switch without tripping. I can turn it by hand, but it gets very hard to turn when it reaches the off time. Sometimes it trips the switch, but only when I force it to by hand. I've read other reviews and this is a common problem with this timer. I would not recommend. There are digital timers out there for not much more. ## Frequently Bought Together - NSi Industries TORK 1109A Indoor 40-Amp Multi-Volt Mechanical Lighting and Appliance Timer - 24-Hour Programming - Multiple On/Off Settings - 120/208-277-Volt - Grey 2.9 x 4.7 x 7.9 inches - Pair of 2 Tork P47 - Trippers - 1 on and 1 off - for 1100, 7000, and 1800 Series - Time Switch Replacement Trippers 1 On and 1 Off --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/65176977-nsi-industries-tork-1109a-indoor-40-amp-multi-volt-mechanical](https://www.desertcart.sg/products/65176977-nsi-industries-tork-1109a-indoor-40-amp-multi-volt-mechanical) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-10*
