Thanks spdbrake. I'll be going "in search of" tomorrow... and thought with their reputation for brakes... maybe it carries over to their switches. Maybe not... it was just a thought... and I thought I'd try to give the thread another option not mentioned previously.

They're rated at 15 amps... the same amperage used for my brake light circuit (I was surprised that most switches I've looked at today seemed to be 20 amps)... have a closing circuit of 60 to 100 psi (possibly as low as 30 psi)... and fit 1/8" NPT. But... I can't seem to find any info on the threads for the existing one... including the one you referenced.
