I currently have a simple AC 230v doorbell at home - press of button at the door delivers 230v to Bell. I'd like to use a cordless Bell switch outside but the problem is that I don't want to replace the recessed wall button on the wall next to the door, none of the cordless switches fit the niche out even give a strong wireless signal when placed in the wall niche. So instead, I would like to try and place the cordless switch inside the house (basically replace the current Bell with the cordless switch such that
Switch pressed at door -> triggers wireless switch -> wireless Bell rings in another part of house
This would also allow me to extend the range of the bell without having to rewire the whole house.
The problem is that the wireless switch works off a 3v circuit while the current switch delivers 230v, so I think an opto isolated trigger mechanism would be best. Would anyone have a simple yet reliable circuit that I could use?
Thanks in advance
