PURPOSE: A bicolor light emitting diode(LED) lamp is provided to precisely determine the driving state of an operation unit by using the bicolor LED lamp having two contact points, and to easily maintain and control a display unit of a control switch by simplifying the circuit structure of the display unit. CONSTITUTION: Two LED's have different colors. The anode of one of the two LED's is connected to the cathode of the other LED to form the first contact point. The anode of the other LED is connected to the cathode of one of the two LED's to form the second contact point. |
