## Questions & Answers

**Q: Are the contacts able to switch 240 VAC?**
A: It's not designed for that, and 240V could require switching 2 - 120V lines, which would require using two of them, switched by one 12v control circuit.  It might work, but I wouldn't do it - - -

**Q: Will these fit my 2000 jaguar s-type 3.0 v6 ?**
A: They are standard relays for aftermarket wiring of electronics if you are trying to replace a factory relay check the pin location under the relay if they are the same then they should fit

**Q: Are they used in 12volt dc lights for off road vehio**
A: they are used in 12 volt vehicles

**Q: Will these fit a 2001 town & country**
A: not sure .I had to bend the metal tab to close the fuse door

### ⭐⭐⭐⭐⭐ Work just like they should
*by S***5 on February 22, 2026*

They worked perfect

### ⭐⭐⭐⭐ Good relays, but with two issues.
*by G***. on December 10, 2025*

These are generally well made relays with two exceptions. First only 9 of the 10 were useable due to an internal flaw. I tested these with a highly accurate bench top multimeter and got around 0.04 ohms resistance from 30 to 87, the NO contact that closes when energized, which is what you would expect when the coil is at room temp. One of them however, was bouncing from 0.3 to 0.5 ohms which is not good at all. Also there is the issue of the mounting bracket. These brackets should be designed to hold securely but also be able to be removed. These are not removable without cutting the plastic. I had to cut the plastic on all eight relays I used and then use a chisel to pry the plastic up so I could remove the bracket. Never had to do that before.
