The latest firmware of the FutureNow Ethernet dimmer and relay modules support standard (maintained) switches on the inputs. Now you don't even have to bother finding momentary switches for your installations. Besides, people that are used to conventional light switches will not need to get used to momentary switches when switching to an automated home. If dimming is not needed (holding and letting go of a maintained switch is not possible) just select "switch" input mode and use any standard switch.
