ABSTRACT:
An automatic controller comprising a supporting structure, a plurality of adjustable contacts, and a selector mounted for movement on the supporting structure for sequentially engaging each of the contents. The adjustable contacts are mounted on the supporting structure for movement relative to each other along a path from a relatively stacked condition to a relatively fanned out condition. In the fanned out condition, each adjustable contact can project beyond at least one adjacent adjustable contact a variable amount so that the extent of exposure of each adjustable contact can be adjusted. The selector sequentially engages the exposed portions of the contacts to sequentially make and break a plurality of circuits.
