Electromagnetic switch, time-adjustable controller and toaster

An electromagnetic switch, comprising:

• a base (1),
• a first static contact piece (2),
• a second static contact piece (3),
• a movable contact piece (4),
• a movable member (5),
• an intermediate driving member (6), and
• an electromagnetic driving assembly (7),
• wherein the first static contact piece (2) and the second static contact piece (3) are fixed on the base (1), and the second static contact piece (3) is spaced apart from the first static contact piece (2), wherein the movable contact piece (4) is arranged between the first static contact piece (2) and the second static contact piece (3), wherein the movable contact piece (4) is electrically connected to the first static contact piece (2), wherein the movable contact piece (4) further comprises an on-off portion (41), wherein the on-off portion (41) is arranged on an upper side of the second static contact piece (3), wherein the movable member (5) is rotatably connected to the base (1), wherein the movable member (5) is arranged on an upper side of the movable contact piece (4), wherein the movable member (5) further comprises a first action portion (51), wherein the first action portion (51) is arranged on one side of a rotating shaft connecting the movable member (5) and the base (1) that is close to the first static contact piece (2), wherein the intermediate driving member (6) is arranged between the movable member (5) and the movable contact piece (4), wherein an upper side of the intermediate driving member (6) is connected to the movable member (5), and a lower side of the intermediate driving member (6) is connected to the movable contact piece (4), wherein the intermediate driving member (6) is configured to be capable of propelling the on-off portion (41) to move up and down along with the rotation of the movable member (5), so that the on-off portion (41) is capable of moving down to contact the second static contact piece (3) or moving up to be away from the second static contact piece (3), wherein the electromagnetic driving assembly (7) further comprises a coil (71) and a magnetic core (72) capable of moving up and down, wherein the coil (71) is fixed on the base (1), and the magnetic core (72) is arranged on a lower side of the first action portion (51), wherein when the coil (71) is electrified, the magnetic core (72) moves up to push the first action portion (51) up, wherein the first static contact piece (2) and the second static contact piece (3) are switched between an on state and an off state by means of the movable member (5), the intermediate driving member (6), the movable contact piece (4) and the electromagnetic driving assembly (7), wherein in an on state, the coil (71) is not electrified and the magnetic core (72) is at the lower position, wherein at this point, the first action portion (51) is at the lower position, which enables the intermediate driving member (6) to propel the on-off portion (41) to move down to contact the second static contact piece (3), so that the first static contact piece (2) and the second static contact piece (3) are connected, wherein in an off state, the coil (71) is electrified to generate a magnetic force to attract the magnetic core (72) to move up, wherein at this point, the upper side of the magnetic core (72) pushes the first action portion (51) up while enabling the movable member (5) to rotate, which allows the intermediate driving member (6) to propel the on-off portion (41) to move up to be away from the second static contact piece (3), so that the first static contact piece (2) and the second static contact piece (3) are disconnected.
