info sought on RACAL MA.295 change-over switch
 

Hello all,

I got a RACAL MA.295 antenna change-over switch I would like to use.
It has on the front 3 N connectors labeled "antenna", "receiver" and
"transmitter" and a fuse holder plus 2 lamps (power on and transmit).
Inside is a transformer plus some diodes, a relay and a big coaxial
relay.
I do not want to rip up the wiring, so I was wondering if somebody
happens to have documentation of this thing.
