If you go down the flic button route you could replace the ‘dumb’ switch with a security light one (http://www.amazon.co.uk/White-Emergency-Lighting-Double-Switch/dp/B007GMO8W6) that way the wiring is still the same but you can only turn the lights off by inserting a key so fine for maintainance/resets etc but not going to be accidentally presseed, then stick the flic button next to the switch for everyday use.
