Top 3 Customer Questions & Concerns ‍

1. Is this relay suitable for switching household AC power?

   • It is rated for 0.5A at 250VAC, which is suitable for small AC signals or very low-power devices. For heavy appliances like heaters or large motors, you will need a higher-amperage relay.

2. Can I mount this directly on a prototype board?

   • Yes, the 4-pin through-hole design is fully compatible with standard universal prototype PCBs like our HS-02 (7cm x 9cm) series.

3. What does "Normally Open" mean for this relay?

   • The "1A" (SPST-NO) designation means the circuit is disconnected by default. When 12V is applied to the coil, the contacts close and complete the circuit.
