the tumbler switch can be found in motor or industrail control panel it will look like a handle outside of the door panel but inside will look like " open " drum switch with large number of concats.
this is very common on older control panels but newer one are controled by plc system but however for some still used the tumbler switch on it currentally. [ not too widespread ]
the last time i did see tumbler switch was in power control panel [ for multi generator units ] it have 12 lead connected to the " drum " switch
hope it help you with this
Merci, Marc
