Abstract

1468072 Relay interlocking CUTLERHAMMER EUROPA Ltd 17 July 1974 [19 July 1973] 31713/74 Heading H1N An interlock for preventing the simultaneous closure of a pair of switches mounted on opposite sides of the interlock comprises a frame 10 with a port 12, 14 suspended therefrom to be in the path of movement of both switch armatures and retained further in the path of one armature when the other is moved to its actuated position. The interlock may be a single thermoplastic mounting with edge rib 30 and flexible part 16 as well and locking parts 22, 24, 26, 28 for engaging its recesses in the switch cases (Figs. 3 and 6, not shown).
