Motion Control Switch- triggering Elwire project- need HELP Answered

I have a motion controlled light switch that activates a glowing aqua elwire arch. It lights up when anyone approaches the hallway. Problem is that the switch is allowing 3 volts through even when there is no motion. This measly 3v is enough to power the inverter and light the elwire. How can I add 3v of resistance to block that leakage?

I called Leviton, maker of the motion switch. 2-3v leak is normal for that. They recommend using their other motion switch which uses a relay. Unfortunately it's a $56 switch.

Or you could add a relay to your current switch. A relay won't trigger with the leak and would open the contact when not activated. The only concern is that the current out of the switch be strong enough to both power the relay and the light.

To add some resistance, you could say add... A RESISTOR!! Alternatively you could use a diode. Silicon diodes typically have a 0.6V drop, so you could keep adding them in series until you drop below the forward voltage for the EL wire

Or an LED so you know it's on.

A 3v or 4v LED in parallel?

I'd suggest you try to repair the switch rather than jury-rig it. The most common cause for a device like this to fail are failing filter capacitors. A failing capacitor would cause low or fluctuating power to the entire circuit. Look for one or two large can capacitors in the power supply section of the device. Replace them with exactly the same capacitance (marked MFD or uf), the voltage should at the very least match, but I would select one rated for a higher voltage to avoid future failures. Make sure that the capacitors are installed with the same polarity as the old.
