Abstract

1,260,027. Retractive switches. WILD ROVER CORP. 12 Dec., 1969 [30 Dec., 1968], No. 60848/69. Heading H1N. A retractive switch comprises a flexible contact element having a flexible portion of effective length L and a plurality of contact segments, these being separated from a fixed contact by a distance, d, less than 0À008 inch, such that the ratio d/L is less than 0À02. In Fig. 3, the touch operated switch has a flexible plate 52a which has wires 54 fixed to it, these being positioned over two terminals 46, 48 and separated by less than 0À008 inch and preferably between 0À0025 and 0À004 inch. The plate 52 may be of brass with the wires 54 of silver cadmium oxide. The terminals 46 and 48 may be brass with a silver cadmium oxide coating. The plate rests on a ring 50 acting as a heat sink and has a disc, e.g. of phenolic resin, 56, placed over it and also a clear film 58, these being retained in position by a rim 40a. In Fig. 8 the flexible plate is replaced by a corrugated flexible element 90 having wires 92 fixed to the bottom peaks. A stabilizer plate 96, positioned over the member 90, is moved by an actuator 98, supported by springs 100, such that the wires bridge the terminals associated with screws 86, 88. The manner of attachment of the stabilizer plate to the element 90, Figs. 12-16 (not shown), affects its flexibility in both lateral and transverse directions. The corrugations of the contact member also affect the flexibility, Figs. 17-26 (not shown). More than one flexible member and more than two base terminals may be included in each switch assembly, this multipole assembly decreasing the possibility of arcing by increasing the number of series connected gaps.
