Are you looking for an original A-7? They're difficult to find and when you do, they tend to be a bit more pricey. I have an A-9 for mine. Typically, they can be rebuilt with minimal effort.

Jim,

How can I tell the difference between an A-7 and A-9? I'll post a picture tonight.

John,

Thanks for the link!

The A-9 switch has a battery position (BAT) which the A-7 does not. I don't have one in front of me, but IIRC some are labeled with the model number in the outer band. Some aren't.

A-7 switches are pretty simple and can be rebuilt. That is your best option as they are extremely scarce. The pop up on eBay occasionally, but a rough used one will typically bring $150 and a refurbished one is over $200. A-9s are only slightly less.

I have an A-9, but it has a small handle. I'm going to use it as it is all I have at the moment. Still looking for an A-7.

Bigred, mine did the same thing. I took it apart and cleaned the contact areas, working fine for 22 years now. Pete Jones (Air Repair) linked above has a kit for $275.00 I would clean the contacts before I'd spend $275. Also make sure the wires from the switch to the mags have continuity.
