ABSTRACT:
A controller for an electrical switching device such as a motor starting contactor including separable contacts, an operating mechanism for operating the separable contacts and a control mechanism responsive to a plurality of control sources for controlling the operating mechanism, includes a plurality of light emitting diode indicators each of which corresponds to one of the control sources; a membrane pushbutton; and a selection circuit, responsive to the pushbutton for selecting one of the control sources, including a circuit for detecting actuation of the pushbutton; a circuit responding to the actuation for sequentially indicating representations of at least some of the control sources on the corresponding ones of the indicators; and a circuit for detecting de-actuation of the pushbutton to select one of the control sources the representation of which is indicated on the corresponding one of the indicators at the time of the de-actuation.
