I want to replace a simple toggle switch on an existing two-way lighting circuit with a dimmer switch. Is is possible for this to be done on one of the switches only, and if so how does one go about it?
Make sure dimmer will fit in the wall box, or be prepared to change it.
Dimmer should have three terminals same as the existing switch. make sure which is which. one of the terminals connects to one or other of the remaining two, depending on switch positiion.
