Abstract

1298893 Inertia-actuated switches; contacts DYNAMIT NOBEL AG 31 July 1970 [1 Aug 1969] 37224/70 Addition to 1281652 Heading H1N In a vibration-sensitive electric switch of the type described in the parent Specification, the deformable projection 9, Fig. 3, of the fixed contact after being deformed (as shown) by impact from the moving recessed contact 4 remains with its end 13 in permanent engagement with the inner wall of the recess 10. The projection 9 may be of tin or of tin alloyed with combinations of antimony, silver and gold. At least one of the contacts may alternatively be of lead or a synthetic plastics material having an electrically conductive layer.
