We installed the switch and set the switch to toggle at the correct airspeed, and checked the operation. The switch worked positively as advertised. Thank you George Boggs President Boggs Avionics Inc.

After installing this switch, there was a leak in the aircraft static system. I traced the leak to this switch. The static port on the switch is vented to the interior of the switch case. And the case is not airtight. I disconnected this airspeed switch from the static system and vented the switch to the cabin instead. I had also purchased a 40 knot airspeed switch and it leaked through the case too.
