The 12V 10A SPDT Power Relay (SRD-12VDC-SL-C) is a rugged electromechanical relay that uses a 12V coil to switch AC or DC loads up to 10A, making it a common choice for automotive circuits, home automation, and 12V-powered relay modules. Its single-pole double-throw contact and 5-pin THT footprint drop straight into standard relay driver PCBs.
Key features:
- 12V DC Coil: Matches common 12V battery, solar, and automotive control circuits.
- SPDT Contact: Provides both Normally Open (NO) and Normally Closed (NC) terminals for flexible wiring.
- High Switching Capacity: Rated 10A at 250VAC/125VAC and 10A at 30VDC/28VDC.
- 5-Pin THT Mounting: Solders directly into PCBs and pre-built relay modules.
- Sealed Plastic Housing: Compact “sugar cube” body resists dust for reliable long-term use.
- Fast Switching: Millisecond-range operate and release times.
It pairs well with Arduino, ESP32, or transistor driver circuits for controlling 12V-powered lights, pumps, and motors from low-power logic signals.
