Additionally this part will reset itself after it cools down (I tested this feature) whereas the part I was replacing was "one and done."Cheap - but I don't know what I am going to do with the other 4! (junk drawer I guess...). Would be nice to be able to buy just one. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Exactly what I needed to fix my clothes steamer! *by M***R on Reviewed in the United States on October 17, 2024* Saved me a lot of money not having to buy a new steamer. This was an easy fix! Fantastic build quality and functionality. Accurate product description. ### ⭐⭐⭐⭐ 4.0 out of 5 stars QC could be better, but not a huge deal. *by R***C on Reviewed in the United States on January 23, 2022* Bought these to repair a small 12v tire air pump. First one out of the package did not work, but the next one worked fine, and the remaining ones do as well (tested them with a meter and heat source). Price is reasonable enough that I am not concerned about the single defective unit. Just posting this in case it helps someone else in the future. ## Frequently Bought Together - RuiLing 5-Pack KSD301 40 Degrees Centigrade Thermostat Thermal Control Switch 250V 10A Normally Closed NC Thermostat Temperature Switch - irhapsody 24V 120AMP Continuous Duty Solenoid Relay, 4-pin SPST High-Power Split Charge Relay - Philmore 5/8" On/Off Key Switch Lock SPST Key Removable On Or Off With 2 Keys and Nut; 30-10078 --- ## 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.co.uk/products/149600544-5-pack-ksd301-40-degrees-centigrade-thermostat-thermal-control-switch](https://www.desertcart.co.uk/products/149600544-5-pack-ksd301-40-degrees-centigrade-thermostat-thermal-control-switch) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
