LED Relay Contact Tester

LED Relay Contact Tester

Description

I use these when I am programming. I connect one to each relay then I can visibly see if the relay is energized. Only need a little soldering and some spare resistor size leads. Use a CR2032 Battery and tape the lid on after assembly. Make the leads long enough to reach into the screw contacts of your relay. :)
