Abstract: The present invention provides for a handle set for a lock with a latch, the handle set having an authentication circuit and actuator in the interior handle that allow access to authenticated transponders. The present invention also provides a device and method for transmitting a rotational movement and force in an electronic lock, wherein the transmission takes place in a coupled state and not in a decoupled state and wherein the transmission of force does not damage an actuator that requires little energy to change between the coupled and decoupled states. A coupling cartridge of an electronic lock can easily be handed. The electronic lock can be retrofitted in installed mortise locks and used with cylindrical locks. The electronic lock can include a security feature that prohibits the electronic lock from changing between the coupled and decoupled states.

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.
