I need an (off)-on or an (off)-on-(off) "push-to-break" switch for residential use
I have a humidity sensing exhaust fan in my bathroom. When the fan has power and senses humidity, it will run the fan until the humidity is removed. If you want to turn the fan on manually (in a stinky situation) you can switch the power off momentarily and then back on and it will run for a pre determined amount of time.
In order to make the fan dummy-proof and to prevent mold from growing, I do not want to give users the ability to turn off power to the fan. I could just eliminate the switch and the humidity sensor would take care of the rest, but then the user would not have the ability to momentarily cycle the power to run the fan manually when there is stink but no humidity.
So what I need is a switch that always springs back to the on position. I have found this type of switch in different physical styles that won't neatly work with a wall plate. I need it to be a typical residential/commercial rocker or toggle switch.
The closest I have come to such a thing is the Leviton 1256 but it's center-off instead of center-on. Is it possible to reverse the function of the switch? Or is there another switch out there that would work better? Or is there another more elegant solution all together that I haven't though of?
