Abstract

926,005. Switch contacts; air-break switches. J. L. GRATZMULLER. Aug. 25, 1959 [Aug. 27, 1958 ; Aug. 24, 1959], No. 29019/59. Class 38 (5). A face-contact make- and-break switch comprises two relatively movable members, of which one movable member 8 has a substantially flat, smooth contact surface of relative hard material and the other member is fixed and comprises at least one fingerlike element 1 whose contact - making extremity at least is of relatively soft material, the or each element 1 being aligned in the general direction of relative movement, and fluid power means for relatively moving the two contact members. Three fingers 1, e.g. of copper, are deformed into good contact with the flat member 8, e.g. of hard bronze, when the switch is closed by means of an hydraulic jack 36, the member 8 being tiltable in any direction. A strong circuit-breaking spring 43 is compressed simultaneously, and rapidly breaks the contact when the hydraulic cylinder 36 is exhausted subsequently. Contact between fingers 1 and member 8 is maintained by a spring 22 at a predetermined pressure sufficient to avoid excessive temperatures due to current heating, the pressure being maintained even if the hydraulic pressure fluctuates, providing the hydraulic pressure is sufficient to overcome the strength of spring 43.
