The 5V 7A SPDT Relay PCB Mount is a compact electromagnetic relay with a 5V DC coil and SPDT contacts rated at 7A, designed for through-hole PCB mounting — the 5V coil voltage is the key practical difference from the 12V relay cube, because the coil can be energised from the same 5V supply used by an Arduino or other 5V microcontroller system without requiring a separate 12V power source. This relay cube is the bare relay component used as the switching element in custom PCB relay driver circuits and relay module builds where the designer wants to select their own driver transistor, flyback diode, and board layout rather than using a pre-built relay module.
The 5v spdt relay’s SPDT contact configuration provides three terminals — common (COM), normally open (NO), and normally closed (NC) — allowing the relay to be wired for either standard switching (load powers on when relay energises via NO) or fail-safe switching (load stays on until relay energises via NC).
The spdt relay cube’s 7A contact rating and 250VAC switching voltage cover the majority of home automation, motor switching, and appliance control loads encountered in Indian maker and STEM projects. This 5v relay pcb mount is ideal for custom Arduino PCB relay driver circuit and through-hole relay switching project builds in India.
