How does a rocker switch work?

In this article, we will introduce the knowledge points about the rocker switch, such as what is the working principle of the rocker switch, what are the parts of the rocker switch, and what do you need to pay attention to.

A rocker switch is a common type of electronic switch, also known as a boat switch . Its appearance and shape resembles a small boat, hence the name of a rocker switch. A rocker switch usually consists of an operator, contacts, springs, terminals, and a housing with internal contacts for connecting or disconnecting circuits. The contacts are usually made of metal, one of which is fixed inside the switch, and the other contact is connected to the operating member, and the contact state between the contacts is changed by the movement of the operating member. The terminals are connected to the external circuit by means of soldering or plugging, etc., in order to transmit the switching state and signals. The enclosure can be made of plastic or metal materials and is used to protect against dust and water and to provide mechanical protection. Because of their internal structure designed for stability, reliability and durability, they are suitable for a variety of applications such as electronic equipment, instrumentation, control panels, etc.

The working principle of a rocker switch is very simple, it consists of a normally closed contact and a normally open contact. When the contact is pressed, the circuit appears to be connected; when it is released, it returns to the previous normally closed contact, known as the disconnect. The force of this pressure is used to close and open the button with our hands. This design allows a rocker switch to perform control, selection, or switching operations in a variety of applications, such as switching electronic devices on and off, function selection, mode switching, and so on.

Rocker switches usually come in a number of standard sizes and specifications to accommodate common applications. These standard sizes can cover aspects such as external dimensions, mounting hole distances, rocker length and shape. However, the dimensions and specifications of a rocker switch are not completely uniform and may vary depending on the manufacturer, model, and specific application. Different manufacturers may offer a variety of different sizes and configurations of rocker switches to meet a variety of needs. For special applications or specific requirements, customized rocker switches are often available as well. Our company can customize the design and provide the required dimensions, shapes, functions and features of the rocker switches according to the customer's needs.
