## Questions & Answers

**Q: What is the AT rating of these switches?**
A: The AT rating is the Amp Turn rating of gauss to activate the switch. Since the vendor does not know this simple term best to stay away from this switch.

**Q: How close do you have to be to set it off?**
A: While using a rather strong NeodymiumBoron magnet, I was somewhat disappointed to find I had to be within an inch or 2.5 cm to get it to close.

**Q: what are the dimensions of the glass tube?  Diameter, approx length?**
A: I'm pretty sure this is what I have; glass part is  .5 inches.
I didn't use them; I found if you put pressure on the tails, they crack.

**Q: Is this latching, or only magnet presence?**
A: These are NOT latching... only close in presence of magnetic field...and does not require much to close. I use these routinely under 1-2 inches of plastic and can still get them to actuate with a very small 1/4" neodymium magnet.
