Abstract
An assembly is disclosed for permitting the transmission of an electrical signal between areas. A housing defines first and second areas having different pressures. A sleeve threadingly engaged with the housing defines a port, and an electrically conductive button is disposed at least partially in the port. An input wire extending into the port is connected to the button at a first point, and an output wire is connected to the button at a second point and extends into the second area. A first compressible insulator is disposed between the button and the housing, and a second compressible insulator is disposed between the button and the sleeve. An insulative O-ring is disposed between the first insulator and the second insulator, and a third insulator is disposed between the sleeve and the second insulator.
