ABSTRACT:
A switch mechanism for visually indicating whether the switch is turned on or off includes a button having a hole and being depressable to turn the switch on or off. A rotatable indicator includes a first color portion that is positioned in the opening when the switch is turned on and a second color portion that is positioned in the opening when the switch is turned off. An indicator controller is coupled to the button and the indicator and carries the contacts for the switch. The indicating controller moves the indicator to position the proper colored portion in the opening in response to the opening and closing of the switch contacts by the depression of the button.
