About this product
A fully sealed SPDT (1 Form C) PCB relay from the SRD series, used to switch loads from a low-power control circuit. The listed contact load is 5A/30VDC and 5A/250VAC. The title states a 9V coil, but the listed specifications give a 12VDC rated coil, so confirm the coil voltage before use.

Frequently asked questions
What coil voltage does this relay need?
The title says 9V, but the listed specifications give a rated coil of 12VDC, pull-in 8.4V and release 1.2V. Confirm the coil voltage from the marking on the relay body or the manufacturer datasheet before wiring it.
How do I drive this relay from a microcontroller?
Based on the listed 530mW at 12V, the coil draws about 44mA, which is more than a typical GPIO pin can supply. Switch the coil with a transistor or MOSFET and place a flyback diode across the coil.
