Two Way Switches?

[luis84]

Hello Everyone,

Forgive me for being new.  I want to convert some lights in my house.  I have hallway lights that have 2 switches, one upstairs and one downstairs.  I want to be able to control those with x10.  Can I simply replace one of the switches with a normal x10 switch or do I need a special 2 way switch? Is it just a normal switch?

Thank you

Both switches have to be changed.
One actually controls the load and the companion places a control signal on one of the traveler wires from the original three way setup to the master switch controlling the load.

Wiring diagrams are in the PDF files here:

Hello,

So a three way x10 switch is what I need?  3 way means it is actually 2 switches like I described?

Thank you

If both switches control the same set of lights. Yes that is what you want.
Since X10 has shifted its business model. You may find some devices discontinued or with a steep price increase.
