I was hooking up an aftermarket intermittent wiper timer this weekend.
No problem hooking it up but I got to wondering while looking at the switch;
What do the numbers on the spade terminals of switches represent?
For instance, 53, 31b etc.
I also noticed numbers when resoldering relays, ie 85, 87/2, 86/1, 30 etc.
The numbers are obviously there for some reason, but what?
Is this some type of electrical code?
Just wondering on a cold NE day.
Any ideas?
