An actuating mechanism for effecting the ejection of an electronics card from an electrical connector has a reduced cost, reduced component wear, simple assembly, and compact space-saving structure. The actuating mechanism includes a rotary shaft that engages with or disengages from an ejection mechanism for loading and unloading a card, and exerts an ejection force to the ejection mechanism when the rotary shaft engages with the ejection mechanism. Switching between engagement and disengagement is effected by rotation of this rotary shaft, and the rotation is effected by the interaction of wave-shaped cams provided on the rotary shaft and on an axially slidable pushrod.
