Some of my older ones, are operated buy a rheostat, so there is only one OFF-position. Others have selector switch positions like 0 thru 11 and if you park between any position, it will turn off. So all you have to do, is just stay off your preferred position and with little effort, turn it on. ....I'm not sure how to operate all the red-dots you guys use, but mine can be turned on and off in a split second, so that isn't a factor for me.
