Hello,

 

I have a switch Box with 3 switches, each switch goes to a different light, these lights are ONLY controlled by these three switches, there are no other light switches for these lights.

 

In the Switch Box , there are 4 Romex wires coming in.

 

The color code on these wires is ,,,White , Black and Copper (Ground)

 

I assume 3 of these wires go to the lights

 

1 of these wires is likely the feed , load or source

 

All Blacks are together 

All Whites are together

All Copper(Grounds are together

 

The 3 switches all have 2 black wires going to them 

 

On the switches:

One of the Black wires is wire nutted with all the black wires together

 

And one of the black wires returns to the light (into the wall) I assume

 

And again all the Whites are wire nutted together

 

I want to replace 1 of these switches with a HS200, is this the right device ?

 

The HS200 has 2 blacks a White and a Ground

 

I have actually tried a couple different configurations with the HS200 and either the light stays on , or stays dim and when on goes bright,

Obviously I am not making the correct connections, and do not want to cause an issue.
