The short answer is NO. This would need to control a relay that you would use in the kill circuit as this device is limited on the power it is able to handle. **Q: Could this be used as a reverse light switch on a side by side?** A: Yes but you will need to add some electronic circuitry for this. **Q: Does this need to use a resistor between V+ and Data out? If it does, what resistor did you use** A: A pull up resistor wasn’t needed for my application --- ## 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.th/products/453019778-hiletgo-2pcs-njk-5002c-hall-effect-sensor-proximity-switch-npn](https://www.desertcart.co.th/products/453019778-hiletgo-2pcs-njk-5002c-hall-effect-sensor-proximity-switch-npn) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-25*
