Yes, when the key is turned 1/4 to the right the switch is fully engaged and when you release it will spring back to "off" position. The key is also removable (spare key included).

I don't have a HS (or any System 11's) to test with but I did test fit with a few WPC games. There's a small keyed notch in the top that keeps the mod from spinning when the key is turned. As long as that cutout exists on the sys 11 cab the mod should work.

I've got about 6 of these left in stock if anyone else is interested.

I hope everyone who has received them so far is enjoying them.

I should have more for sale by the end of the week. I'll update this thread when they are back in stock. Sorry for the delay.

Back in stock again:

If anyone is curious to see it in person, the key mod will be on display at Texas Pinball Festival this weekend.

I'll have a few more made up this week. Probably Monday or Tuesday.

Do you know if the cabinet style is the same as Tron? I have access to a Tron, I could try it and let you know.

I may have a few mountain "seconds" in my storage unit. Send me a PM if you're serious. I've been very sick with the flu though so my apologies if I'm slow to respond or make it to storage.

The seconds have been added to Etsy. They contain minor cosmetic imperfections in the paint but once installed not noticeable in my opinion. Photos taken of each one so you can judge for yourself. A lot of people have repainted them so if that's your plan these should work well for you.
