Abstract
842,089. Mercury switch contacts. ENGEL & GIBBS Ltd. April 24, 1957 [April 27, 1956], No. 13051/56. Addition to 793,173. Class 38 (5). [Also in Group XX] A tilting switch of the type described in the parent Specification has a tubular envelope 10 with a pair of electrodes 13, 14 projecting through each of its end walls 15, one electrode of each pair projecting into the envelope a greater longitudinal distance than the other electrode such that movement of the conducting liquid 12 (which is preferably an amalgam with thallium, as described in Specification 793,174) breaks one circuit before breaking the other circuit, or makes one circuit before making the other. The electrodes are pointed to give good electrical connection with the conducting liquid which is normally in connection with a central electrode 16 entering the envelope from an end wall (Fig. 1), or a side wall (Fig. 2). Specification 798,336 also is referred to.
