The abutment (1) has a connecting unit to secure the actuating abutment to a switching device (100), and a contact zone to cooperate with an upper blade of a blind resting against the contact zone, so as to produce a movement of the actuating abutment by the upper blade of the blind when the actuating abutment is fixed to the switching device. A gripping unit and a driving unit allow another actuating abutment (1') to be driven under the effect of force applied to the gripping unit. Independent claims are also included for the following: (1) an actuator for internal or external motorized blind blades (2) a method for replacing an actuating abutment. |
