Claim 0:
1. A pivoting electrical cam lock comprising,
a base with a cylindrical open bore having a first end and a second end and defining a first axis, a rotating mechanical lock in the bore having a keyway at one end proximate the bore first end and an actuator at the opposite end proximate the bore second end, the lock adapted so that when a proper key is inserted into the keyway and rotated, the lock and actuator rotate with the key in the base bore about the first axis,
a cap fixed to the actuator and adapted to rotate about the first axis with the actuator and mechanical lock, the cap having a bore defining a second axis parallel to the first axis,
a cam radially extending from the cap, the cam having a first side and a second side and a cylindrical aperture extending through the cam from the first side to the second side, with the aperture coaxial with the second axis,
an electric motor fixed to the cap and having a rotating drive shaft extending outwardly therefrom, the drive shaft having a longitudinal axis coaxial with the second axis and extending into the cap second bore, with the drive shaft adapted to rotate in response to an electrical signal to the motor,
a slip clutch connected to the drive shaft for rotation therewith, with one side of the slip clutch biased against the cam first side,
wherein the cam pivots about the second axis in response to the electrical signal to the motor, and the cam pivots about the first axis with the cap upon rotation of the proper key in the mechanical lock.
