Abstract

An adjusting shaft for an electric regulating or control device, which operates equipment functions by means of a control cam, is profiled to engage the control cam and can be installed subsequent to the complete assembly of the control device and fixed relative to the control device by a spring detent and associated stop. The stop can also serve to prevent unintentional rotation of the control cam until displacement of the stop against the opposition of a biasing spring. The subsequently installed shaft can allow use of universal control devices with random shaft lengths and types.
