SPDT 12V PCB Relay (Sugar Cube)
The SPDT 12V PCB Relay (Sugar Cube Type) is a compact and reliable electromechanical switch designed for controlling high-voltage or high-current loads using a low-power 12V DC signal. Its miniature "sugar cube" form factor makes it ideal for PCB-mounted applications where space is limited while maintaining excellent switching performance.
Featuring a Single Pole Double Throw (SPDT) contact configuration, this relay provides COM, NO, and NC terminals, allowing flexible control of electrical circuits. With a robust contact rating of up to 7A–10A (depending on model), it is widely used in automation systems, microcontroller projects, home appliances, industrial controls, power management circuits, and DIY electronics projects.
