Summary:To provide: an electromagnetic operation mechanism that does not require a mechanical guide and that brings out the best of the maintenance properties of an electromagnetic device; and a power switch provided with same. [Solution] An operation mechanism provided with a row of an outer permanent magnet (31), a row of an inner permanent magnet (32) , and a floating output ring (34) that is arranged between said rows and that has a three- phase coil (33) wrapped therearound. The floating output ring (34) does not possess a mechanical restraint relationship with other members within a linear electric motor (3). Instead , a controller for controlling a PWM inverter that injects alternating excitation current into the three- phase coil (33) controls the d -axis current component of the excitation current so that magnetism causes supporting force with respect to the floating output ring (34) to be generated and the central axes of the floating output ring (34) and a double cylinder (35) are aligned.
