US Patent 11193309 Electronic sensor and key operated lock

An electronic sensor and key operated lock is disclosed which provides users with the option to use at least one of a manually operated mechanism or for example a biometric sensor to unlock the lock. The lock integrates both the manually operated mechanism and a biometric sensor into one device. The manually operated mechanism and a biometric sensor are coupled to a common toggle switch so that operation of at least one of the manually operated mechanism and the biometric sensor moves the toggle switch and a shackle from locked and unlocked positions.
