Teardown of a RADIALL R570152010 12V latching coax relay.  I am trying to fit an auxiliary contact or position indicator to allow my sequencer to know the current state of the relay.  The relay has 80dB isolation and handles 500W at 1.3GHz.

The controller PCB is double-sided and contains protection diodes and (possibly) pulsed drivers, not checked that yet.

That projecting pin looks like it would operate an aux contact.  Perhaps I could use it to run a Hall sensor, or some contacts cannibalised from a small DC relay.
