Im currently studying for my NEN3140 exam and I stumbeld acros this image:
I have been poking around in google (and all the symbol questions I could find here) and the closest I got is this (page2):
which makes me this it is a "Switch, general symbol double pole", after googleing som more I can find the top right symbol back as a double pole switch
But I can't find the "key/switch" with 4 bars/poles? back. Is it safe to think this is a 4 pole switch or is it somthing else?
