The invention discloses a mechanical switch and a spine massage correction device controlled by the same. A sliding sleeve is controlled only through a sliding block; a sliding rod controls a first spring, a ball drops into an arc-shaped groove in the sliding rod, a third spring extrudes a second sliding block, and the second sliding block moves relative to a first sliding block and extrudes a telescopic pole, thereby achieving the spear knockout target; and meanwhile, a second spring on the telescopic pole deforms and the telescopic pole automatically restores to an original position, and so on, thereby achieving the target of spine-hitting massage correction. The control principle is simple; a spine massage device for carrying out spine-hitting massage by using the mechanical switch is simple in structure, not easy to heat and large in hitting force; the spine massage device can carry out hitting operation for a long period of time; the problem of fast heating of a magnetic field mode is solved; the operation is smoother; the physical therapy time is shortened; and the physical therapy effect is improved. The mechanical switch is compact in design and light; and in addition, internal parts are reduced and the production cost is reduced.
