The interlock switch has 3 positions, if you push it down or PULL IT UP, it is on, in the middle position it is off.
You just have to pull it up to the maximum.

I surely have a spare coin mechanism, I will look after it soon.
By the way, we have a special Dragon's Lair Fans credit switch for the games that dont have free play mode.


Some pictures from the Scorpion bootleg would be great, I didn't know that it exists.
