The 5V 10A SPDT Power Relay (SRD-05VDC-SL-C) is a compact electromechanical relay that lets a low-power 5V signal from an Arduino, ESP32, or other microcontroller switch mains-level AC or DC loads up to 10A. Its single-pole double-throw contact and 5-pin THT layout make it a go-to building block for relay modules, home automation, and DIY switching projects.
Key features:
- 5V DC Coil: Triggers reliably from standard 5V logic and relay driver circuits.
- SPDT Contact: Offers both Normally Open (NO) and Normally Closed (NC) switching in one relay.
- High Switching Capacity: Rated 10A at 250VAC/125VAC and 10A at 30VDC/28VDC.
- 5-Pin THT Mounting: Solders directly into PCBs and relay driver boards.
- Compact Sealed Body: Dust-resistant plastic housing suited for breadboard and enclosure use.
- Fast Response: Operates in a few milliseconds for snappy on/off switching.
This relay is a staple building block for anyone assembling their own single or multi-channel relay boards for home automation and control projects.
