An electromagnetic switch, comprising:
- a stationary contact;
- a movable contact movably provided with respect to the stationary contact;
- a coil configured to move the movable contact to a side of the stationary contact by current conduction;
- and
- a shaft provided inside the coil such that the movable contact is provided at an end portion thereof,
- wherein a snap-fit portion having a pair of hooks disposed to face each other is provided at an end portion of the shaft, and the movable contact is fixed between the end portion of the shaft and the pair of hooks,
- wherein a distance between the pair of hooks and the end portion of the shaft is greater than a thickness of the movable contact such that the movable contact is movable with respect to the shaft, and
- wherein the electromagnetic switch further comprises a push spring disposed between the end portion of the shaft and a rear surface of the movable contact to exert an elastic force in a direction to cause the movable contact to move towards the stationary contact.
