The ActiveMetal switch has three wires – how do I install this?
An ActiveMetal switch is truly a touch sensor programmed to function as a switch. The Red (+VDC) and Black (-VDC) wires are the input power connections to the switch. The Green wire is the output that either changes voltage or resistance based on the type of ActiveMetal sensor being used. More explicit wiring schemes can be found at: www.activemetal.
