No instructions. Found them online. Switch does not function. Don’t waste your money on this garbage. ### ⭐ Misleading description - 120C max temperature, not 500C! *by A***R on 27 February 2026* Misleading description. This is not a K-type, 500C controller. Upper temperature limit is 120C, despite what the title said. The title and description are misleading. If you need temperatures above 120C, find a K-type controller. Unfortunately, I already installed this one and can't return it. ## Frequently Bought Together - Temperature Controller 12V 500C Dc 12V Led Digital Thermostat Electronic W3230 Led Digital Temperature Controller Thermostat Switch Sensor Meter(Dc12V ) (12V red and Blue Display) - Fielect Gear Motor DC 12V 7RPM High Torque Electric Motor Micro Speed Reduction Geared Motor Eccentric Output Shaft for Car Robot Model DIY Engine - Twidec/6Pcs Round Rocker Switch AC 6A 125V 10A 250V SPST 3 Pins 2 Position ON/Off Red and Green LED Light Illuminated Round Boat Rocker Switch Toggle KCD1-5-101NRG --- ## 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.in/products/753066869-temperature-controller-12v-500c-dc-12v-led-digital-thermostat-electronic](https://www.desertcart.in/products/753066869-temperature-controller-12v-500c-dc-12v-led-digital-thermostat-electronic) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-07-02*
