I'm looking at relays and there are multiple types of contacts forms, such as: A, B, C, X, Y, Z and much more. Searching around found different schematics for same form.
Can someone explain them or show me a picture of the different contact forms?

There is a mesh in symbols because even manufacturer agree on a common language, marketing issues differentiate them frequently.
Even the common assosiation RELAY AND SWITCH INDUSTRY ASSOCIATION I think it is not existe anymore, but they are publish a handbook about relays, the "Engineer's Relay Handbook"
Bellow is en extract of the above handbook (5th edition) the types of contacs are available throught the market.
