## Questions & Answers

**Q: How is this wired: to a transmitter?  to the garage opener? Why 28V?**
A: It's a simple switch, more for someone knowledgeable about basic electronic components.  You could hook it up to a power supply and a light, to turn on a light when it the magnet is nearby.  Or you could hook it up to a smart house hub designed to take in simple signals. 

It's not just 28V, it's 0V-28V (simple answer, more volts = more heat = higher chance of fire.  bigger wires reduces heat/volt, but increases cost of device, so they limit it to a chosen level, in this case 28V)

**Q: Is this a normally open or closed switch?  One reviewer said they received a normally open switch... but you state in the specs that its NC.**
A: Closed when magnet engaged
