Contact makers for emergency alarms WWII submarines

Hi, I am an old sub sailor. I served on a WWII diesel boat(USS Carp SS-338) in the sixties. I was stationed in Norfolk. The Navy decommissioned the USS Guavina (SS-362) and was going to take her out and use her for target practice. We were told we could have anything we wanted off the boat so I took 2 diving alarms. Someone beat me to the contact maker switches for the alarms. As I was leaving the Guavina an officer off of our boat saw me with the 2 alarms and told me to put them in his cabin. This was just wrong and I was pissed but I did it. After fuming about it I went back later and took one back. It is sitting in my garage at the moment. I would love to find the contact switch for it. Any thoughts on where, if anywhere, I might find one?
