## Questions & Answers

**Q: Does the module draw current when in the open state?  If so, how much current is drawn.**
A: I haven't measured it's current draw when the relay is off, but I could almost bet this only takes a few milliamps.  That 8-pin controller chip is not going to draw much energy.  The biggest current draw is when the relay coil is turned on - probably 80 or 100 mA for the coil.

**Q: Will this switch reset if the dc power is removed?**
A: Yes they revert to default when power is removed

**Q: Is this limited to a 30v dc application or can i use this to switch my 12v dc devices? if so, what is the amp rating for a 12v dc device? thanks!**
A: Contact Type	Normally Open
Current Rating	10 Amps
Brand	HiLetgo
Coil Voltage	12 Volts
Contact Current Rating	10 Amps
Maximum Switching Current	10 Amps

**Q: How would one orient a polarized 0.1uF capacitor in the momentary switch circuit?**
A: If you are suppressing transients then the cap should be connected between line and ground in a DC circuit.
