Disclosed is an apparatus for displaying state and transition state information of mechanical equipment. A sensor and display system is provided for displaying aircraft landing gear status and other mechanism status. In one embodiment, the system utilizes two light emitting diodes (LEDs) for each landing gear leg to display the current position of each gear leg. One yellow LED indicates gear UP and the second green LED shows gear DOWN position. When the control switch is moved to change the position of the gear, the indicator light which had been lit is extinguished, and the indicator for the desired position begins to flash, indicating gear movement. The indicator will continue to flash until the gear leg has reached the limit of travel, at which time the indicator stops flashing and glows steadily. Each gear leg indicator operates independently of the others, so that proper position of each gear leg can be confirmed and any malfunction can immediately be identified. In another embodiment the indicator light glows steadily while mechanical equipment is in a transition state, and the light flashes when the mechanical equipment reaches a desired position.

[ What is claimed is:] [1.] An indicator system for displaying a state and a transition state of a mechanism comprising:a power supply;a single light source for displaying the state and the transition state;a sensor switch in contact with the mechanism at the state, the sensor switch having a common contact connected to the power supply, and having a normally closed contact and a normally open contact from which to route power;a resistor connected between the normally open contact and the light source; anda flashing diode connected between the normally closed contact and the light source,whereby to indicate the state, the mechanism contacts the sensor switch and the sensor switch actuates the normally open contact and causes the light source to indicate steadily, andto indicate the transition state, the sensor switch actuates the normally closed contact and causes the light source to indicate intermittently.
