A unique combination of nonvolatile memory (16) with a visual indicator (18) to give a device an address display which adds very little cost or space to the device and its housing. A nonvolatile RAM incorporated into the device electronics is provided with a memory location sufficient for storing the identifier in binary form. A simple visual display in the form of an LED (18) is also provided in the device housing and electrically connected to the RAM for providing visual indication of the stored number according to a predefined code.

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.
