The structural characteristics of the button switchThe structure of the button switch: It is composed of a button cap, a return spring, a fixed contact, a movable contact, a shell and a pillar connecting rod.Normally open contact (moving contact): refers to the contact in the original state (the electrical appliance is not subjected to external force […]
Precautions for using button switchesThere is a big difference between the button switch capabilities in AC and DC circuits, and the control capacity is very low in DC applications. This is mainly because DC does not have a zero point like AC, so it is difficult to eliminate the arc once it occurs, and the arc […]
Classification of button switchesButton switches can be classified according to operation mode and protection mode. Common button categories and characteristics:Open type: suitable for embedded installation and fixed on the panel of the switch board, control cabinet or console.Protective type: With a protective shell, it can prevent the internal button parts from being mechanically damaged or people touching […]
The basic concept of metal push button switchMetal push button switch is a kind of power supply that uses modern power electronic technology to control the timing ratio of switch tube registration and turn off to maintain a stable output voltage. Metal push button switches are usually composed of pulse width modulation control ICs and MOSFETs. […]
Push button switch has the advantages of small contact resistance, accurate operating force error and diversified specifications. They are widely used in electronic equipment and white household appliances, such as video and audio products, digital products, remote controls, communication products, household appliances, security products, playing equipment, computer products, fitness equipment, medical equipment, banknote checking pen, […]
Push button switch is a kind of electrical appliance that acts when pressed and resets when released, which is used to turn on and off small current circuits. It is generally used in the control circuit with AC / DC voltage below 440V and current less than 5A. Generally, it does not directly operate the main […]
