Abstract
Disconnection of a fluid conduit from a fluid fitting 38 and electrical conduit from apertures 28 in a fluid pressure sensing switch when servicing is required is avoided in a construction wherein a switch module 12 is secured to a base 10 mounting a fluid pressure receiving fitting 38 and electrical conduit receiving apertures 28 by only two threaded fasteners 24, allowing the module 12 to be separated readily from the base 10 without disturbing conduit connections.
