An electromagnetic switch, comprising:
- a housing, having an accommodating room with a hollow top;
- an electromagnetic unit, including a coil seat and an actuating plate, the coil seat being disposed in the accommodating room, the actuating plate being pivotally connected to the coil seat, the actuating plate having a linking end and a magnetic end, the actuating plate being pivoted back and forth by an external force;
- a contact unit, including a contact seat and at least two electrode sheet assemblies, the contact seat being disposed in the accommodating room, the contact seat having a plurality of movable contacts thereon, the electrode sheet assemblies being respectively located on two sides of the contact seat and extending out of a bottom of the housing, one of the electrode sheet assemblies communicating with the coil seat, the electrode sheet assemblies having a plurality of immovable contacts thereon, the contact seat being against the linking end of the operating plate and sliding up and down through the external force, wherein when the contact seat slides upwards, the movable contacts are in contact with the immovable contacts to turn on electricity;
- when the contact seat slides downwards, the movable contacts are separated from the immovable contacts to turn off electricity;
- a button unit, including a top seat, a power-on button and a power-off button, the top seat being connected to the housing in a snap-fit manner, the power-on button being slidably connected to the top seat so that the power-on button slides up and down relative to the top seat, the power-off button being slidably connected to the top seat so that the power-off button slides up and down relative to the top seat;
- wherein when the power-on button is pressed, the contact seat is driven to move up;
- wherein when the power-off button is pressed, the contact seat is driven to move down;
- a display light, including a circuit board, a light-emitting member and two conductive wires, the circuit board being fixedly connected to the top seat and located below the power-on button, the light-emitting member being disposed on the circuit board, the two conductive wires being connected between the circuit board and one of the electrode sheet assemblies, wherein the conductive wires each have a top flat section, a vertical middle section, a flat middle section and a bottom vertical section from top to bottom, the top flat section is generally horizontal and has one end connected to the circuit board, the vertical middle section is generally vertical and has one end connected to another end of the top flat section, the flat middle section is generally horizontal and has one end connected to another end of the vertical middle section, the bottom vertical section is generally vertical and has one end connected to another end of the flat middle section, and another end of the bottom vertical section is connected to the electrode sheet assemblies.
