Claims

[Scope of utility model registration request]

The plunger, which is attracted when the electromagnetic solenoid is energized and protrudes by the spring force when it is deenergized, and the spring work together to drive the movable contact member in the stroke direction of the plunger, and the contact portion is connected to the plunger and the movable contact member. In an electromagnetic switch that brings the movable contact member into contact with or separates from two fixed contact members located between the movable contact member and facing the movable contact member and spaced apart from each other, the movable contact member is formed in a diaphragm shape. Flange-shaped contact portions are provided on both sides of the open end of the cylindrical portion, and the stroke thereof is set to be shorter than the stroke of the plunger, and the cylindrical portion is loosely inserted between the fixed contact members and its end face is connected to the The spring is placed opposite to the end surface of the plunger and housed within the cylindrical portion;
When the plunger is sucked, the end face of the plunger is separated from the end face of the cylindrical portion, and the movable contact member is brought into contact with each of the fixed contact members, and when the plunger is protruded, the end face of the plunger is moved away from the end face of the cylindrical portion. An electromagnetic switch characterized in that the movable contact member is separated from each of the fixed contact members by pressing an end face of the movable contact member.
