Abstract
An electric time switch mechanism is provided comprising a plurality of units each having an operating thermal expansion member, for example, a bimetallic member. Electrical heating means are provided for the thermal expansion member and a switch is activated by the thermal expansion member. The units are connected in series in such a way that the activation of a switch turns off the heating means of the associated thermal expansion member and turns on that of the following units. The switches remain in the activated state after activation and are resettable by external activation.
