An electromechanical push to close latch has a pawl 49 positioned for linear movement in a housing, with the pawl being biased to the outward extended position. An electric motor 69 operates a cam 95 to change the position of the pawl thereby retracting it into the housing. An electronic circuit board 59 controls the operation of the electric motor under the direction of an outside control signal. The circuit board also senses the position of the pawl to stop the operation of the motor when the pawl is fully retracted. The pawl mounting can be reconfigured for the pawl to extend and thereby operate in a plurality of selectable directions - for example in fig. 8 where housing portion 47 containing the pawl has been turned through ninety degrees with respect to housing portion 45 containing the motor 69 and reduction gears. Cam 95 engages onto a splined hub 91 of an output gear and engages into a pawl cavity. |
