## Questions & Answers

**Q: Can this be used as a high limit switch to turn off the heater or gas valve.  What is the range of temperature.**
A: Sorry No this is not a limit switch http://www.amazon.com/gp/product/B00ESH2Z2W Take a look at the link above limit switch

**Q: Will this switch work on a 12 V DC system? Thank you.**
A: Yes - it's just a switch. Make sure you don't exceed a reasonable 12V current - 10A would be safe. My usage is at 24V, 5A.There is no published rating for DC operation on Amazon. You should check the manufacturer's web site or call them if you want to switch a very large current.

**Q: Is this a low limit switch ?**
A: Hello. This is a BRAND NEW ADJUSTABLE (90-130 degree) 1 Pole fan switch! It makes connection anywhere between 90 and 130 degrees (wherever u set it at) and usually is designed to bring on a Blower Motor! The differential is 20 degrees! Look at your fan switch and you should find the temperature rating of yours listed on the switch itself!

**Q: We have a propane Country fire place.. we need a F140-20f.   610049 vent safety snap switch.  Will this switch showen work for our fan control?**
A: Not a Professional HVAC guy. But that is what I bought these for a friend for. To turn on his fan on his wood stove. however we discovered that te stove did turn on the fan. but where it was located caused it to fail after 2 days. it was to close. but a fireplace  may be different.
