2 doorbells with one switch
Hi, I have two doorbells that I want to trigger with a switch. One of the doorbell has cordless remote and the other is wired. I need your advice whether the following diagram is ok..My only concern is the difference between 4.5v and 12V..Are they okay to mix together? Thanks!!

You would need a two pole switch so the voltages could be kept separate.

So there is no way I could mix those 2 cables?
Is there push button switch with double pole? Thanks!

Yes, it just isn't sold specifically for doorbells and you will have to figure out a mounting for it. Probably a small plastic project box will work.

Hi Just one last question.. Suppose I have 2 wires that run the same voltage, I can put them together in one pole switch?

Yes, but only if from the same source. Best to use a relay controlled by the doorbell button for what you are trying to do.
