12V SPDT PCB Relay

The 12V SPDT PCB Relay is an electromagnetic relay designed for switching high-voltage or high-current loads using a low-voltage control signal. It is widely used in Arduino projects, automation systems, home appliances, power supplies, industrial control, and DIY electronics. The relay features a 12V DC coil and Single Pole Double Throw (SPDT) contacts, allowing you to control AC or DC loads safely.
