How to choose rocker switch?

Rocker switch is a kind of mechanical switch, its main function is to control the opening and closing of the circuit, often used in household appliances, electronic equipment, automobiles and other fields. This paper will introduce the product introduction and working principle of the rocker switch in detail.

The rocker switch is usually composed of parts such as a shell, a contact, a spring, a rocker arm, and a conductive plate. Its shape styles are round, square, rectangular, hourglass shape, etc., with different sizes and colors, can be customized according to customer needs. The contact material of the rocker switch mainly includes copper, silver, palladium, alloy and other materials, of which silver contact has the best electrical conductivity and palladium contact has the longest life.

At the same time, according to the different use conditions, it can also be divided into direct acting warping switch and Angle acting rocker switch. The former works by pressing the trigger to control the opening and closing of the contact, the latter works by turning the trigger to control the opening and closing of the contact. In addition, there are surface mount (SMT) rocker switch and socket rocker switch according to the installation method.

The working principle of the rocker switch is very simple, when the external force acts on the trigger, the trigger will drive the rocker arm on the warping plate, so that the contact contact with another contact (fixed contact), the circuit is connected, and the appliance begins to work. When the external force is removed, the spring will spring the rocker arm back to the original position, so that the contact is separated from the fixed contact, the circuit is cut off, and the electrical appliance stops working.

Rocker switch is a very common electronic component, widely used in home appliances, automobiles, medical devices, game consoles and industrial control fields. Its advantages mainly lie in:

1. Low price, easy to manufacture;

2. Small size, easy to install and maintain;

3. Light switch action, long service life;

4. Reliable function, stable work, can adapt to the needs of different electrical and electronic equipment.

The above is the product introduction and explanation of the working principle of the rocker switch. In daily life, we may ignore this little switch, but in fact, it does take on important tasks and play an irreplaceable role. If you've seen the concept of a warped switch when buying electrical and electronic equipment, then hopefully this article will help you.
