Product works but the toggles suck
The on/off buttons failed super fast but it did the job.

Works as it should! I used to jump the fuel pump with the key off on my 4.0L jeep. I had a fuel pressure problem where the regulator would bleed pressure off. This allowed me to hook up a gauge, turn the fuel pump on which should bring it to 29-31 psi and hold it in the rail. The regulator would not, as the o-rings bypassed fuel to return. This relay set helped me figure that out. Sure I could have just used a piece of wire to jump it, but a toggle is nice to have.

Work says designs must be careful with the circuit you are testing

I've used these in the field to diagnose electrical issues more than I'd like to admit to. Works every time.
