I've got a commercially made three position remote coax switch, that I'd 
like to get more information on, if someone has it.

Made by Amphenol
Model number 3BNI20R10A-7 (don't know if that I is a 1 or not)
Serial: 6419
28 Volts DC

Has 5 connections on it
3 BNC (outputs)
1 Type N Female
1 bluk-head with 3 pins.

Does this mean that if you pulse 28v on one pin, it goes to the right, 
and if you pulse the other 28v pin, it turns to the left, with the last 
pin at ground potential?

Pins are marked A B C

other indentifiers are stamped on the unit...


those are stamped on, so may be a local part number, wherever it came from.

Any help?  Google wasn't.

73 = Best Regards,
