Claim 9:
10. The security device according to claim 9
wherein the lock control circuit further comprises a plurality of microswitches;
wherein each of the plurality of microswitches is an electric switch;
wherein each of the plurality of microswitches is a momentary switch;
wherein each of the plurality of microswitches mounts in the slotted structure formed in the locking structure;
wherein each microswitch selected from the plurality of microswitches is positioned in the slotted structure of the locking structure such that each selected microswitch interacts with the toothed structure of a blade selected from the multi-blade structure of the key structure;
wherein each microswitch selected from the plurality of microswitches presses against the toothed structure of the blade selected from the multi-blade structure such that the movement of the selected blade past the selected microswitch moves the position of the selected microswitch such that the microswitch is actuated by the toothed structure;
wherein the logic circuit monitors the actuation of each of the plurality of microswitches;
wherein the specific actuations of each of the plurality of microswitches by the toothed structures of the multi-blade structure is used by the lock control circuit to identify that the inserted key structure is authorized to release the locking structure.
