<p>A small-sized power load-break switch is provided while increasing the transmission efficiency of force. The rotation of the drive shaft of a drive mechanism is transmitted through an input spur gear, a cylinder roller, and a rotational lever, etc., rather than converted to a linear motion, to an actuator attached fixedly to an output shaft. The transmission of motion between the cylinder roller and the rotational lever is carried out by the engagement of the side of the cylinder roller with a closed cam hole formed in the rotational lever.</p> |
