SRD-12VDC-SL-C Relay 12V DC Coil, 10A, SPDT, 220VAC, 5 Pin
Product Overview
The SRD-12VDC-SL-C from Pro Tronix is perhaps the most widely used relay in the world of hobbyist and professional electronics. It is a miniature electromagnetic power relay designed for PCB mounting, offering a perfect balance between size and power handling.
With its 12V DC coil, it is natively compatible with automotive electrical systems and common 12V power supplies. The SPDT (Single Pole Double Throw) configuration provides one Common (COM) pin that can switch between a Normally Open (NO) and a Normally Closed (NC) contact, allowing for versatile circuit design—whether you are making a remote-controlled light switch or a failsafe motor kill-switch.
