Household electrical appliance control, lighting control family, factory equipment control, used to control a variety of small current control for high voltage and high power products. Parameters: Power supply voltage: 12V Power supply current: more than 100mA Load: 250V 10A (AC) or 30V 10A (DC) Life: 1000000 times How to use: 1 .According to the direct power supply voltage connected to the correspondingversion; 2. Power supply according to the line graph of the requirements, can not bereversed, although the protection circuit, but not for a long time to reverse; 3. Using a voltage stabilizing tube (5V no voltage regulator tube) a slight fever, is a normal phenomenon, relay working long hours also have normal heatingphenomenon, is a normal phenomenon; 4. Load power to relay load leave some margin, should avoid high power (about 2000W) and long time working environment, will have a certain impact on the service life of the product.

If so, how much current is drawn.** A: I haven't measured it's current draw when the relay is off, but I could almost bet this only takes a few milliamps. That 8-pin controller chip is not going to draw much energy. The biggest current draw is when the relay coil is turned on - probably 80 or 100 mA for the coil. **Q: Will this switch reset if the dc power is removed?** A: Yes they revert to default when power is removed **Q: Is this limited to a 30v dc application or can i use this to switch my 12v dc devices? if so, what is the amp rating for a 12v dc device? thanks!** A: Contact Type Normally Open Current Rating 10 Amps Brand HiLetgo Coil Voltage 12 Volts Contact Current Rating 10 Amps Maximum Switching Current 10 Amps **Q: How would one orient a polarized 0.1uF capacitor in the momentary switch circuit?** A: If you are suppressing transients then the cap should be connected between line and ground in a DC circuit. ## Frequently Bought Together - HiLetgo 2pcs 12V Single Bistable Self-Locking Relay Module Push to Start and Stop - AEDIKO 4pcs DC 12V Relay Module 1 Channel Relay Board with Optocoupler Isolation Support High or Low Level - HiLetgo 2pcs DC 12V 2 Channel Relay Module with Isolated Optocoupler High and Low Level H/L Level Trigger Module Triggered by DC 12V --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/45094942-hiletgo-2pcs-12v-single-bistable-self-locking-relay-module-push](https://www.desertcart.pt/products/45094942-hiletgo-2pcs-12v-single-bistable-self-locking-relay-module-push) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-25*
