Regarding the different types of push button switches, there are certain differences in their structure, so what are the differences in the structure of different types of button switches? The normally open contact is also called the moving contact, which means that in the initial state, the electrical appliance does not have Under the condition of external force, the fixed contact and the movable contact can also be in a separate state.
The normally closed contact is also called the moving contact, which refers to the contact in which the fixed contact and the movable contact are in a closed state under the same initial condition of the electrical appliance and will not be subjected to external force.
Normally open button switch, the contact is broken when it is not pressed. When the thick contact is pressed, it will be closed and turned on. After releasing the button, the switch will be under the action of the reset spring. Reset disconnected. In the control circuit, the push switch is also used to start the motor, so it is also called the start button.
The normally closed button switch is just the opposite of the long open switch. When it is not pressed, the contact remains closed. When it is pressed, it will be reset and closed under the action of the reset spring.

Composite push button switch, it is a push button switch that combines normally open and normally closed push switches together, with normally closed contacts and normally open contacts. When not pressed, the normally closed contact is closed, and the normally open contact is broken. When the button is pressed, the normally closed contact will be automatically disconnected, and the normally open contact will be closed, we can feel that this is a self-locking button. When the button is released, the push switch will break the normally open contact and close the normally closed contact under the action of the reset spring. Such push-button switches are often used in interlocking control circuits. Therefore, different types of button switches have different structures and different functions.
