do helicopters have touchdown relay switches?
Aircrafts have touchdown relay switches to deactivate weapons, landing gear, radar, etc. This is usually activated when the stuts compress. I'm just curious about helicopters, especially those without struts.

Some of the wheeled helicopters have squat switches on the gear struts. I don't know for sure, but I would imagine both the Chinook and the Blackhawk have them. Likely not to deactivate weapons systems, but as on civilian machines, to deactivate the Hobbs meter.

I have never heard that one either. As far as the hobbs time that is usually don't with a switch on the oil pressure for engine time and one on the collective for airframe time. As far as I nothing like that on MIL spec helis.
