Claim:
1. A state and operation indicator for a snap switch having a common, a normally closed and/or a normally open terminal, comprising: a common connector providing electric communication between the common terminal at one end of the common connector and a printed circuit board at an opposing end of the common connector, wherein the printed circuit board is configured to be positioned proximate the snap switch; and a first light emitting device and a first light emitting device driver attached to the printed circuit board, wherein the first light emitting device is powered through the first light emitting device driver; wherein, irrespective of whether the normally open terminal is closed or open, and irrespective of whether the normally closed terminal is closed or open, when the common terminal is energized, current is transmitted through the common connector, printed circuit board, and first light emitting device driver to the first light emitting device, which in response emits light; and a normally open connector providing electric communication between the normally open terminal at one end of the normally open connector and the printed circuit board at an opposing end of the normally open connector; and a second light emitting device and a second light emitting device driver attached to the printed circuit board, wherein the second light emitting device is powered through the second light emitting device driver; wherein when the switch is activated, the normally open terminal closes causing current to pass through the normally open terminal, the current is transmitted through the normally open connector, printed circuit board, and second light emitting device driver to the second light emitting device, which in response emits light; and a wire terminal connected to the printed circuit board and a power supply for sinking currents which pass through the light emitting devices.
