📝 Short Product Description
The Songle SRD-05VDC-SL-C is a highly reliable, compact 5-pin miniature power relay designed for PCB mounting. Featuring a 5V DC coil and a Single-Pole Double-Throw (SPDT) configuration, it allows low-voltage microcontrollers like Arduino or ESP32 to safely control high-power circuits up to 10A at 250VAC or 30VDC. It is the perfect choice for smart home automation, DIY electronics projects, and appliance repairs.
✨ Bulleted Highlights
- High Load Capacity: Switches loads up to 10A (250VAC / 30VDC).
- Microcontroller Friendly: Low-power 5V DC coil trigger voltage.
- SPDT Interface: Features 1 Common (COM), 1 Normally Open (NO), and 1 Normally Closed (NC) pin.
- Compact Footprint: Miniature T73 cube design saves valuable PCB board space.

📄 High-Converting E-Commerce Product Description
SONGLE SRD-05VDC-SL-C 5V DC 10A 5-Pin Mini Power Relay (SPDT)
Maximize your project control with the authentic Songle SRD-05VDC-SL-C Power Relay. This heavy-duty, compact electromagnetic switch is a global industry standard for low-voltage logic circuits. It acts as an isolated bridge, allowing microcontrollers like Arduino, ESP32, Raspberry Pi, or PIC to safely trigger high-voltage household appliances and industrial machines.
Engineered with a Single-Pole Double-Throw (SPDT) configuration, it features one common input pin that alternates output paths between a Normally Open (NO) terminal and a Normally Closed (NC) terminal based on whether the internal coil is energized.
