Abstract

1,224,878. Fluid actuation of switches; moving-magnet switches. ROTAX Ltd. 4 June, 1968 [9 June, 1967], No. 26740/67. Heading HlN. Pressure of fluid admitted to bore 11 via a filter 14 acts on a piston 15 having a stem 17 with a knife-edge coupling to a beam 18 pivoted at 19 and carrying a permanent magnet 23 for operation of a reed contact device 24. The operating pressure is controllable from the exterior of the housing 10 by adjustment of the anchorage (22, Fig. 3, not shown) of a torsion spring 21 acting on the stem 17. The piston 15 has a curved skirt 16 to prevent binding in the bore 11 due to tilting, and a drainage aperture 25 allows escape of fluid leaking past the skirt 16.
