You're right. It is all in what you're used to. Circle bar W can be tuff to work on - 40 year old cold solders, the PIA 2 hour job of changing a 45 or NA/NB relay, speck of dust in an ES relay contact shutting a car down... At least they had the sense to put in a hand/auto and door switch! These old Otis and Dover units that you have to pull a freaking wire off of terminals that the markings have rotted off is about beyond stupid. All they had to do was install $2 toggle switch to make a mechanic's routine so much easier. I've been trying to get switches installed over the years on my O and D equipment in my spare time, trouble is I don't have any spare time.
