Tenshodo Switch Machines

I have Tenshodo switch machines on my layout and one of the switches is missing the contacts on the side. Does anyone have any Idea where I can get contacts to replace them? Any info would be great Thanks in advance!!

NJ International made simular machines but they no longer sell them. They would work if you can find any. Some machines had two ā€œAā€ contacts and some had ā€œCā€ contacts. Mounting a small microswitch on the machine may be another answer.
