ABSTRACT:
An electrochemical counting device in a casing, which contains counters that may be switched by a drive. The drive is connected to a switch armature, which engages a stepping wheel to shift the counters. The drive is also provided with two swivel arms, which are not mechanically connected. Each swivel arm is equipped with a spool. In order to shift the counters, both swivel arms are pivotable oppositely directed in a synchronized manner, perpendicular to the pole face of the permanent magnet. The permanent magnet is arranged between the two swivel arms. Both swivel arms are supported at the casing by a spring. The swivel arms cannot be pivoted accidentally towards each other due to impact and therefore cannot accidentally shift the counters. The electromechanical counting device may therefore be employed, where sudden impact or magnetic interference may occur.
