Uses
The most common use for cam timers is in automatic washing machines, where they are used to drive the washing sequence according to a pre-programmed pattern. They are gradually being superseded by microprocessor-controlled systems, which have greater versatility, and thus can more easily respond to various feedback.
Historically, cam timers were employed on industrial machines to control repetitive sequencing operations. In this case the cam followers often operated hydraulic valves. Cam timers in industry were superseded with the introduction of PLCs, which offer improved reliability and allow the operation to be optimised.
