Abstract
Disclosed is a convertible motorized latch that may be configured in either of a slam latch or a dead bolt latch configuration, just by desired selection and replacement of a minimal number of components, and which may be used on new (oem) equipment or in retrofit applications. In either preferred configuration, an electric motor contained within the latch housing operates to open or unlock the latch. Latch closure may be provided by spring actuation in a slam configuration or by further motor operation in a dead bolt configuration. Either present configuration may make use of an electrical feedback switch for signaling latch retraction while the dead bolt configuration may also include a second electrical feedback switch for signaling latch extension. A gear train may be incorporated within the latch housing to provide reduced speed and increased torque from the electric motor.
