The output voltage would match the input voltage, not increase or decrease it. **Q: Is this a continuous duty relay ?** A: As far as I know it is, I used it to replace my cars blower relay and when that's on it stays on until the end of the drive 20 min to 2 or 3 hours. So I would say yes. **Q: Does this relay make a sound when it closes/opens the circuit?** A: Yes it does when you install it and turn on the item or you can test it with a 12 volt source, if it doesn't make a clicking noise than it is no good and needs to be replaced. **Q: What amperage rating is this relay?** A: Hi, I looked on the relay and did not see a amperage rating. I used it for my tc40 tractor. it was used for the glow plugs so it may be on the higher side. good luck, don ## Frequently Bought Together - BOSCH 0332019110 Normal Open Mini Relay - 4 Pins, 12 V, 30 A - Single - True Mods 10 Pack - Bosch Style 12V DC 5-PIN SPDT Interlocking Relay Socket Harness Base (with Wires) - BOSCH 0332209150 Changeover Mini Relay - 5 Pins, 12 V, 20/30 A - Single --- ## 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.hk/products/78829522-bosch-0332019110-normal-open-mini-relay-4-pins-12-v](https://www.desertcart.hk/products/78829522-bosch-0332019110-normal-open-mini-relay-4-pins-12-v) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-11*
