Vszerda 5PCS Relay HF3FF-005-1ZST 5V 5PIN 12A/125VAC
Pack of five 5 V, 5-pin relays rated 12 A at 125 VAC for switching circuits
- 5 relays included for multi-project builds
- 5 V coil voltage suits low-power control circuits
- 12 A switching capacity handles mains-level loads
- 125 V AC rating covers standard household circuits
Five-piece 5 V relay pack
This pack contains five HF3FF-005-1ZST relays, each with a 5 V coil and five pins. They suit hobbyists and technicians building or repairing low-voltage control circuits. The new components arrive ready for through-hole soldering or socket mounting. Each unit switches up to 12 A at 125 V AC.
Rated for 12 A resistive loads at 125 V AC
The contacts handle typical mains-powered lamps, fans or small heaters within that current limit. Coil voltage is fixed at 5 V, so the relays cannot be driven directly from 12 V or 24 V sources without external circuitry. They are not suited for loads exceeding 12 A or for higher-voltage switching.

Questions about this item
Will the 5 V coil on the HF3FF-005-1ZST work with the 5 V logic rail on my existing Arduino board?
Yes, the relay is the 5 V variant and its coil is designed for a 5 V control signal, matching a standard 5 V logic rail.
How can I verify the contacts are switching correctly after wiring the 5-pin relay?
Apply 5 V across the coil pins and listen for the audible click; then measure continuity across the normally-open and common pins — it should show a closed circuit when energised.
