description The invention discloses a magnetic type emergency stop button used on an explosion-proof shell. The emergency stop button comprises a key sleeve with a sliding channel, a key shaft which has one end arranged in the sliding channel and can slide in the axial direction of the sliding channel, a reset spring which is used for resetting the key shaft, and a locking device which comprises a first magnetic attraction part arranged at the top of the key sleeve and a second magnetic attraction part arranged on the key shaft; when the heteropoles of the first magnetic attraction part and the second magnetic attraction part are opposite, the key shaft is pressed down to be locked; and the key shaft is rotated, so that the same poles of the first magnetic attraction part and the second magnetic attraction part are opposite, and the key shaft is bounced off for unlocking. According to the magnetic type emergency stop button used on an explosion-proof shell, locking is carried out through heteropole attraction of the perm
