Description
This is an alarm keyswitch. It is branded Sonitrol, but it is an Ademco switch and Ademco key. I was not able to locate a model number so I can't be sure of it's vintage. From my experience in the alarm system field it would likely be from the 1970's to mid 1980's. I do not have a pin out for the switch or any instructions. The key clicks in 3 positions two of which you can remove the key from so it appears to be a 3 pole switch. A continuity tester and about a half hour of time in the hands of a skilled technician should be more than enough to figure out how it works.
