Daydreaming again about replacing my ByeBye Standby in-ceiling dimmers with the Fibaro Dimmer module but I can't figure out what light switch I should be using.

The BBSB in-ceiling dimmer sits in close to the light, wired with 3 wires, and are controlled by a 'stick on the wall' remote switch. Behind the switch, I've just connected up the 2 ends of wire with a terminal block.

I've figured that the Fibaro dimmer would be an excellent replacement for the above, but I struggle to understand if I should be using a momentary switch, or a normal switch? And can anyone recommend a nice looking (white) range of switches?
