Abstract

821,385. Pressure actuation of switches. HINN, H. J. Aug. 2, 1957, No. 24534/57. Class 38 (5). [Also in Groups XXXIV and XXXVI] In an electrical tyre deflation indicator arrangement wherein a pressure-responsive switch 24 mounted on the wheel rim is actuated on a fall in tyre pressure to close a circuit to a warning lamp (see Group XXXIV), the switch 24, Fig. 12, comprises a cylindrical body 85 which is screwed at one end 86 into the wheel rim base 18 so that its inner face lies flush with the inner rim surface. The body 85 has inner and outer coaxial bores 90, 91 separated by an annular flange defined by an intermediate bore 89. Within the bores 89-91 is mounted a plunger 92 having an enlarged inner end portion 93 which seats on the annular flange and terminates in an enlarged head 94 which bears against the tyre inner tube 20 through the medium of the rim liner 88. The plunger is urged towards the tube 20 by a spring 95 acting between the annular flange and the plunger head 94. The outer end of the plunger is provided with a contact ring 96 which, on spring movement of the plunger due to fall in tyre pressure, contacts the head 100, a terminal bolt 99 extending transversely through, and insulated from, the wall of the body bore 91, the bolt 99 being electrically connected by a lead 25 to the warning lamp. A cap 24 closes the outer end of the switch body 85.
