Abstract

An electronic access control device with an actuator that requires little energy to change between the coupled and decoupled states. The actuator can have levers that interact to bias the control actuator in the decoupled state. The actuator can be changed between coupled and decoupled states by magnetizing and demagnetizing an armature that interacts with the levers. The electronic lock can include a security apparatus that prohibits the electronic lock from changing between the coupled and decoupled states when an external magnetic field is applied.
