<p>The present invention relates to an actuator assembly, which includes: an upper case; a lower case; an actuator disposed between the upper and lower cases; a cam coupled to the actuator; a shutter connected to the cam; a hook; and a microswitch. The cam includes protrusions and recesses, which are alternately arranged at an interval of 90°. One end of the hook alternately contacts the protrusions and the recesses according to the rotations of the cam, and the other end thereof is coupled to a spring. The longitudinal middle of the hook protrudes so as to form a touch part, and a hook shaft is coupled to a portion between the touch part and the second end of the hook. The microswitch is disposed at the upper side of the cam in order to stop the actuator in accordance with the contact of the microswitch with the touch part. According to the present invention, the actuator assembly has a simple structure, and can be accurately controlled. In addition, improvements in sealing performance and durability can be achieved. Furthermore, since the actuator assembly can be controlled using the single microswitch, a reduction in the cost and in the proportion of defects thereof can be achieved.</p> |
