1. Is a slam/tilt switch ..... kills the game if someone is beating on the door.
2. Is a lockout coil ..... when power is off on the machine it rejects all coins so no-one loses their money in a machine that is turned off.
3. The coin counters do count all coins inserted into the machine, usually require external power source, some are 12v, some are 24v. There's write-ups around on how they can be wired to existing coin switches. They're not "needed".
4. The test switch would put the game into Test Mode to check for errors, switches, settings, etc.
What kind of system are you planning to use this coin door with ? MAME ?
(I did not read your whole other thread)
Cool artwork though. But should have been done in Crimson & Cream.
