💡 What is a 12V SPDT automotive relay used for in car circuits?
This handy device lets you switch high-current accessories from a low-current trigger.
- High-current loads such as lights, fans, and winches can be controlled by a low-current switch
- SPDT configuration enables normally open or normally closed wiring
- 12V DC coil with 1.8 W coil power supports microcontroller or relay modules
- Up to 40 A switching current at 14 V DC ensures compatibility with automotive accessories
