(1) Protective button(push button switch): a button with protective shell, which can prevent the internal button parts from mechanical damage or people from touching the live part. Its code is h.

(2) Dynamic off button(push button switch): under normal conditions, the switch contact is a button for on.

(3) Dynamic closing button(push button switch): under normal conditions, the switch contact is a button that is disconnected.

(4) Dynamic on-off button(push button switch): under normal conditions, the switch contact has both on and off buttons.

(5) Button with light: the button is equipped with signal light, which is not only used to issue operation command, but also used as signal indication, and its code is d.

(6) Action click button: that is, click the button with the mouse.

(7) Explosion proof button: a button that can be used in places containing explosive gas and dust without causing explosion. Its code is B.

(8) Anti corrosion button: it can prevent the invasion of chemical corrosive gas, and its code is f.

Button switch principle

Button switch principle

Push button switch is a switch that uses the push button to push the transmission mechanism of the machine to make the dynamic contact and the static contact connect or disconnect, and then realizes the circuit replacement through this. Therefore, a full understanding of the principle of button switch can better master the working mode […]

Working principle of inductive proximity switch sensor

Inductive proximity switch sensor is a low cost method for non-contact detection of metal objects. When metal objects move towards or out of the proximity switch, the signal will automatically change, so as to achieve the purpose of detection. Its composition is mainly composed of three parts: amplifier output circuit, switching circuit, oscillator.An oscillator, one of […]

What are the two types of push buttons?

Push buttons come in various types and configurations, but broadly speaking, they can be categorized into two main types based on their electrical contacts and functions: Normally Open (NO) Push Button: In a normally open push button, the circuit is open (no electrical continuity) when the button is at rest or not pressed. When the button is […]
