The leaf looks a bit long on that microswitch. You could try triming it down a little. Are there any other screw holes on the bracket? If so, you could try lowering the switch a little.

Replace the spring while you're at, it looks stretched out.

I added a few suggestions into my previous. I was hoping to sneak it in with a simple edit, but you were too quick on the reply.

I can see that in your pictures. It looks like the leaf is putting too much pressure onto the little black button even when the target is up. Try bending the leaf further down (while drop target is down), so the two screws are touching. This will relieve the pressure on the black button once the target goes back up.

There is a coil on the backside of what's in the photo. When I do the solenoid test to test up/down it will raise drop the target but when I'm looking I see that that metal shaft comes back down each time and will keep the switch always down.

Can you post a picture of the backside (coil)?

That's nomal! The shaft always comes back down.

When the target is up, there is a latch for drop target to hook onto. Hitting the target will knock it off from the latch and the high tensioned spring pulls drop target down, which in return hits the microswitch.

That seems like to be the case here. It looks like the microswitch is being treated as an opto (optical). The WPC uses mainly opto switches, which works backwards from a traditional leaf/micro switch.

Interesting enough, Williams was the first company to use opto switches. They first used them on their drop target banks with their System 11 games (starting with Millionaire).

Check the microswitch's black button. Make sure it clicking when pressed.

If we are talking about the sanctum wall then no, that metal arm is not supposed to trigger the switch on its own. The metal arm is supposed to come down after firing but it’s not supposed to trigger the switch, hence the game thinking the wall is always down. You are likely getting sanctum magnet lock errors too? The switch needs adjusted so only the metal arm doesn’t hit it but the wall coming down does.

There is a common mistake here!

The metal tab is not what is supposed to actuate the switch lever its the tab on the Drop Target that is supposed to do that job.
