The SPDT Relay 12VDC – PCB Mount 5 Pin is a compact electromechanical power relay designed to switch AC or DC electrical loads using a 12V DC coil supply. Featuring a Single Pole Double Throw (SPDT) contact arrangement, the relay provides Common (COM), Normally Open (NO), and Normally Closed (NC) contacts, allowing a single input circuit to switch between two different output paths.

Designed for through-hole PCB mounting, this 5-pin relay is commonly used in automation systems, power control circuits, automotive electronics, home appliances, motor control systems, lighting controllers, security equipment, and embedded electronics. When the 12V coil is energized, the internal electromagnetic mechanism changes the position of the contacts, providing electrical isolation between the low-voltage control circuit and the switched load circuit.

The relay is commonly available in compact PCB relay formats with contact ratings of up to 10A at 250VAC or 30VDC, depending on the specific manufacturer and relay model. Its compact size, reliable mechanical switching, and flexible SPDT contact configuration make it suitable for a wide range of switching and control applications.

FAQ

1. What is the SPDT Relay 12VDC – PCB Mount 5 Pin used for?

The relay is used to switch AC or DC electrical loads using a 12V DC coil supply. It is commonly used in automation systems, motor control circuits, lighting systems, appliances, security equipment, and embedded electronics.

2. What does SPDT mean in a relay?

SPDT stands for Single Pole Double Throw. It means the relay has one Common terminal that can switch between a Normally Closed contact and a Normally Open contact.

3. Can a microcontroller directly control this 12V relay?

No. Most microcontroller GPIO pins cannot directly supply the voltage and current required by the 12V relay coil. A transistor, MOSFET, or relay driver IC should be used, along with a flyback diode across the coil.

4. What happens when 12V is applied to the relay coil?

When the coil is energized, the relay changes its contact position. The Common terminal disconnects from the Normally Closed contact and connects to the Normally Open contact.

5. Can this relay switch both AC and DC loads?

Yes. The relay contacts can switch both AC and DC loads within the voltage and current ratings specified for the exact relay model. The load type and whether it is resistive or inductive should also be considered when selecting the relay.
