How to fix induced voltage + relay insert?

Other Devices & Integrations Lighting & Load Control

I have an insert relay that I just installed on an existing 3-way switch. The problem is that I can’t get the relay to work properly because when the 3-way is switched off, there’s still voltage on the output (about 25v). This causes the insert to think that it is still on.

I think this is called induced/ghost voltage, but ultimately all i care about is how do I fix this? Would a resistor of some sort work?

What is the make and model of the insert?

What type of switches are connected(any with locator/night lights in the switch)?

What type of load do you have connected(incandescent, CFL, LED, dimmable)?

What is the specific nature of the problem, ‘doesn’t work properly’ does not describe your issue?

Induced current is highly unlikely to be your issue.

You need to be more precise in your description. A diagram of how you wired the 3 way to the device would be good too as would a mention of the model of “insert” you are using. Aeotec DSC-27103?

Here are several wiring scenarios for Aeotec: http://aeotec.com/support/1219-micro-switch-wiring-schematics.html

Anyway if you are measuring the output of a switch module with no load connected the meter reading is pretty much meaningless. Most modern DVMs are very high impedance so can measure stray voltage and you shouldn’t try to interpret what that reading means. Make sure the load line is connected and there is an actual load (say a 60 W incandescent bulb) then see what your reading is.
