Rocker Switch

Rocker switches are one of the most commonly used switches in various applications. They are commonly used in automotive and marine applications, but can also be found in a variety of other industries. Rocker switches are available in a variety of styles, colors and configurations.

When selecting a rocker switch, it is important to consider the voltage and current rating of the switch, as well as the number of poles and throws. The style of the switch is also an important consideration. The most common rocker switch styles are round, rectangular, and oval.

What is a rocker switch?

Rocker switches are one of the most commonly used switch types in electrical applications. They are often used to control lights, fans, or other devices that use low-voltage circuits. Rocker switches come in a variety of sizes and shapes, and they can be momentary or maintained.

Typically, rocker switches are momentary, meaning they stay where you put them until you let go of the switch. Maintenance rocker switches, on the other hand, stay where you put them until you flip the switch in the opposite direction. They are widely used in marine, automotive, industrial equipment and household appliances.

What are the different types of rocker switches?

Rocker switches are commonly used to control the power or function of a device. There are two main types of rocker switches: momentary and latching.

Momentary rocker switches are used to turn devices on or off momentarily. They are typically used for functions such as the power button and reset button. Latching rocker switches are used to hold a device in a specific state. They are often used for things like choosing between two different modes or setting the device to stay on or off.

How to Choose the Right Rocker Switch for Your Application?

Selecting the right rocker switch for your application depends on several factors. Here are some things to consider:

Electrical Requirements: Determine the electrical requirements of the application, such as rated voltage and current. Make sure the switch can handle the electrical load of your application.

SPST or DPDT: Determine if you need a single pole single throw (SPST) or double pole double throw (DPDT) rocker switch. SPST switches control a single circuit, while DPDT switches control two circuits.

Lighting: Determine if you need lighted or non-lighted switches. Illuminated switches are useful in low light conditions to indicate the on/off status of the switch.

Actuator Style: Choose the actuator style that best suits your application. Rocker switch actuators come in different shapes and sizes such as round, square or rectangular.

Mounting Type: Consider the mounting type of the switch. Some rocker switches are designed for panel mounting, while others are suitable for PCB mounting.

Environmental factors: Consider the environmental factors to which the switch will be exposed, such as temperature, humidity, and dust. Choose switches that are rated for the appropriate environmental conditions.

Application Requirements: Determine the specific requirements of your application, such as the need for waterproof or dustproof switches.
