Q: Does the Honeywell Hobbs Hour meter pressure switch have a 1/8 Male NPT connection?

Yes, the Honeywell Hobbs Hour meter pressure switch has male 1/8" NPT thread. These thread directly into the 1/8” pressure port on the engine.

Q: What is the max oil pressure this Honeywell Hobbs Hour Meter switch can take?

The operating pressure of this unit is 4 PSI, with a maximum burst pressure of 500 psi.

Q: The distance between the oil pump housing and the oil cooler in my Rotax is very small. What is the length of this switch?

Total length of the Honeywell Hobs pressure switch M4006-4 is approximately 2-1/2 inches.

Q: Is this for certified aircraft?

The Honeywell Hobbs meters were used in many OEM production aircraft. However, they are not FAA Approved. Please check your aircraft parts manual or check with your local A&P mechanic to see if this can be installed in your certified aircraft.

Q: What is the manufacturer part number of the Honeywell hobbs hour meter pressure switch 10-00813?

Model No. M4006-4

Q: So basically I guess this works as a ground and so is it designed to ground two devices or can I use just one terminal and activate my hobs meter my existing device looks just like this except its got one connector on the end and I assume that completes a ground circuit

Its basically a switch that will close the circuit at 4psi. One lead would go to the Hobbs meter and the other to a ground.
