Abstract
A self contained radio frequency identification integrated circuit (RFIDIC) switch. The RFIDIC switch includes a switch housing, a radio frequency identification integrated circuit enclosed in the switch housing and an actuator extending into the switch housing. The RFIDIC is powered by a radio frequency carrier signal. The actuator is movable to a first position and to a second position. The radio frequency identification integrated circuit transmits a signal when said actuator is in one of the positions. Movement of the actuator to the other position alters said signal.
