High Power 3V 15A SPDT (1 Form C) Through Hole Relay for Low Voltage Control and PCB Switching Applications
The SRD 3V 15A 1 Form C high power relay is designed for efficient switching of high-current loads using low-voltage control signals. With a 3V DC coil voltage, it is particularly suitable for battery-powered devices, low-voltage embedded systems, and microcontroller-based applications where minimal drive voltage is required. Despite its low coil voltage, this relay offers a strong 15A contact rating, making it capable of controlling loads such as motors, lighting systems, power supplies, and home appliances. The SPDT (Single Pole Double Throw) configuration allows both normally open (NO) and normally closed (NC) operations, providing flexible switching options.
Featuring a compact form factor of 19.2x15.6mm, this through-hole relay ensures easy integration into PCB designs while maintaining strong mechanical stability. It provides effective electrical isolation between the control and load circuits, enhancing safety and reliability in electronic systems. The SRD series is widely used in IoT devices, automation systems, and DIY electronics projects due to its consistent switching performance and long operational life.
