Title: Balanced magnetic switch assembly with sprung pivots - has central pivot bearing block supported by helical springs
IPC: H01H50/30
Filed: 1988-07-05
Abstract: The energising part of the switch consists of a laminated iron 'E-shape' core (4) with a coil (5) wound on a former which fits over the central part of the core. When the coil is energised a pole-piece armature (14), also made of laminated iron, is attracted to the core. Attached to the lower side of the armature via a bracket (15) is a bar-shaped pivot (13), which forms one end of the balance arm (11). The central pivot is formed by two cylindrical pins (12). The other end of the arm carries the switch operating bearings (10). The central pivot bearing block is supported by helical springs similar to those which provide resistance to the switch bearings (10). The sprung central bearing ensures that there are no false operations of the switch even when it is subjected to several tens of g of acceleration.
