Where to buy replacement coin mech switches?

Here's a pic:

Happs has them, I was just looking there a few minutes ago since I might need those style switches for my own project.

That's what's called the "Busy B" coin switch and is used on the Coin Controls coin doors. Happ Controls sells it as their stock number 42-3257-00 (Coin Controls # 891-1116-16). It sells for around $5.

Happ also sells these switches with a straight wire which can be bent into shape.  I have ordered a few of those, although mine look the same as the one pictured (my mechs are indeed Coin Controls ones).

Thanks, guys.

How should this be wired up?

[Ken Layton]

The terminals to be connected are the very bottom and very top ones.

C - common

N.O. - normally open

[Dougmeister]

Thanks, Ken.  I had the NC and the C both hooked up.

What does "NC" stand for?

Thanks, Ken.  I had the NC and the C both hooked up.

What does "NC" stand for?

normally closed.

[Dougmeister]

Duh.  Brain fart.  Should have figured that one out myself.

Thx.

So what is the NC terminal used for anyway?

[Ken Layton]

In 99.9% of commercial coin-op game applications the normally closed terminal is not used. You only need common and normally open. Originally the normally closed terminal was used in applications such as casinos where this terminal was used for cheating prevention.

Innnnnteresting.  Thanks.
