As we said before, the metal push button switch is a simple and widely used master electrical appliance. Its application fields are wide, such as industrial field, machine tool field, aerospace field, home appliance field, access control system, military field, motor vehicle field, etc.

Although our company accepts customize metal push button switches for various purposes, how much do you know about the structural combination of metal push button switches? The following is a brief introduction to the structural combinations of metal button switches.

1.Normally open contact (moving contact): Refers to the contact in the original state (the electrical appliance is not subjected to external force or the coil is not energized), the fixed contact and the movable contact are separated;

2.Normally closed contact (moving and breaking contact): Refers to the contact in which the fixed contact and the movable contact are in a closed state in the original state (the electrical appliance is not subjected to external force or the coil is not energized);

3.Normally open (moving and closing) button switch, when not pressed, the contact is disconnected, when pressed, the contact is closed and connected; when released, the button switch is reset and disconnected under the action of the return spring. In the control circuit, the normally open button is often used to start the motor, also known as the start button;

4.The normally closed (moving off) button switch is the opposite of the normally open button switch. When it is not pressed, the contact is closed, and the contact is disconnected when it is pressed; when the hand is released, the button switch is under the action of the return spring. Reset closed. The normally closed button is often used to control the motor to stop, also known as the self-reset button;

5.Composite button switch: A button switch that combines normally open and normally closed button switches into one, that is, has normally closed contacts and normally open contacts. When not pressed, the normally closed contact is closed and the normally open contact is open. When the button is pressed, the normally closed contact is first disconnected, and the normally open contact is closed later, which can be considered as a self-locking button; when released, the button switch will first disconnect the normally open contact under the action of the return spring. , and then close the normally closed contact. Composite buttons are used in interlock control circuits.

Our common metal push button switch structure combinations include normally open contacts and normally closed contacts. 28.19A metal button is a patented product which independently developed and innovatively designed by J&V Electronic Science and Technology Co., Ltd. The button surface of the switch can be laser engraved, patterned or luminous text and pattern, which can be customized according to customer requirements.
