Provided is a switch operation mechanism that reduces the weight of a movable section of an operation mechanism and thereby reduces the electrical energy that is required for driving, that achieves a comparatively long stroke, high response, and high speed, that decreases the impact force during stopping of an opening operation, and that is highly reliable. An electromagnetic repulsion mechanism section (10) and a magnetic latch section (20) are fixed between a switch (1) and a spring drive section (30) by a repelling fixed member (11) and a fixed yoke (21). The electromagnetic repulsion mechanism section (10) comprises a repelling coil (12) that is attached to the repelling fixed member (11), a reinforcing plate (14) that is attached to a movable shaft (5), and a repelling ring that is attached to the reinforcing plate (14). The magnetic latch (20) comprises a permanent magnet (22) that is attached to the fixed yoke (21), a latch ring (23) that is attached to the permanent magnet (22), and a movable yoke (24) that is attached on the movable shaft. The spring drive section (30) comprises a support frame (31), a spring-holding plate (32), an opening spring (33), a damper section (40), and first and second electromagnetic solenoids (50, 60). |
