Abstract
A combined pressure responsive electrical switch and temperature sensor device (10, 10′) is shown comprising a base member (12) mounting an electrical switch actuatable by a pressure responsive snap-acting disc (16) attached to a port fitting (22) having an elongated temperature sensing portion (22h, 22h′) extending from the fitting within a threaded bore of the fitting adapted to be inserted in the bore of a fluid pressure source nipple (2). A thermistor (24) is disposed at the distal end (22k, 22k′) of the temperature sensing portion and is electrically connected to terminals (14) of the base member.
