A rocker switch is a type of electrical switch that consists of a lever or rocker that can be toggled between two positions: "on" and "off." Sometimes referred to as an “on-off switch,” these switches are commonly used in various applications to control the flow of electricity to a device or circuit. They are known for their simple operation, ease of use, and distinct "rocking" motion when toggled.

## **IP Ratings for Rocker Switches**

The IP (Ingress Protection) rating of a rocker switch indicates its level of protection against dust and moisture ingress. Rocker switches come with different IP ratings to suit various environments and applications. Some common ones are:

### **IP65 Rocker Switch**

An IP65 rocker switch is dust-tight and protected against water jets from any direction. These switches are commonly used in outdoor applications or industrial environments where the switch may be exposed to dust and water splashes.

### **IP67 Rocker Switch**

An IP67 rocker switch offers even greater protection, being completely dust-tight and submersible in water up to a certain depth. These switches are suitable for harsh environments where the switch may be exposed to heavy dust, rain, or even temporary submersion in water.

### **IP40 Rocker Switch**

An IP40 rocker switch provides basic protection against solid objects larger than 1mm, such as tools and wires. These switches are typically used in indoor applications where there is minimal risk of dust or water ingress.

## **Types of Rocker Switches**

Rocker switches come in a wide variety of types with different features and functionalities to suit diverse applications and user preferences. They can be differentiated:

### **By Contact Configuration**

Rocker switches can be classified based on their contact configuration, which determines how the switch controls the flow of electricity in a circuit.

- **Single Pole Single Throw (SPST) Rocker Switch:** An SPST rocker switch has a single contact that can either be opened or closed, effectively turning a circuit on or off. It's the simplest type of rocker switch.
- **Single Pole Double Throw (SPDT) Rocker Switch:** An SPDT rocker switch has a single contact that can be connected to one of two different circuits. This allows the switch to select between two different paths for the current flow.
- **Double Pole Single Throw (DPST) Rocker Switch:** A DPST rocker switch controls two separate circuits simultaneously with a single rocker action. It's essentially like having two SPST switches in one.
- **Double Pole Double Throw (DPDT) Rocker Switch:** A DPDT rocker switch is the most versatile type, controlling two separate circuits with two different contact positions for each circuit. This allows for complex switching configurations.

### **Illuminated/Lighted**

Illuminated rocker switches provide a visual indication of the switch's status, enhancing user feedback and improving visibility in low-light conditions.

- **Illuminated Rocker Switches:** These rocker switches have a built-in light source that illuminates when the switch is in the "on" position, providing clear visual confirmation of the switch's state.
- **LED Rocker Switch:** LED rocker switches use light-emitting diodes (LEDs) as the light source, offering energy efficiency, long lifespan, and a variety of colour options for customisation and indication.

### **By Mounting Type**

Rocker switches are available in various mounting styles to suit different installation requirements and panel designs, such as:

- **Surface Mount Rocker Switch:** Surface mount rocker switches are designed to be mounted directly onto the surface of a panel or enclosure, providing a simple and convenient installation method.
- **PCB Mount Rocker Switch:** PCB mount rocker switches are designed to be soldered directly onto a printed circuit board (PCB), offering a compact and space-saving solution for integrating switches into electronic devices.
- **Panel Mount Rocker Switch:** Panel mount rocker switches are designed to be mounted through a hole in a panel, providing a secure and robust installation. They are commonly used in industrial control panels and equipment.
- **Snap-In Rocker Switch:** Snap-in rocker switches are designed to be easily snapped into a panel cutout, providing a quick and tool-free installation method. They are often used in consumer electronics and appliances.

## **Applications of Rocker Switches**

Rocker switches are versatile electrical components used in a wide range of applications across various industries. 

### **Manufacturing & Automation**

In manufacturing and automation, rocker switches provide reliable control for various equipment and processes, such as:

- **Control Panels:** LED rocker switches and illuminated rocker switches are commonly used in control panels for industrial machinery, providing a clear visual indication of the switch's status and enhancing operator feedback.
- **Process Control System:** Rocker switches are used in process control systems to initiate or interrupt processes, control the flow of materials, and provide operator interfaces for managing automated systems.
- **PLC Panels:** Surface mount rocker switches are often integrated into programmable logic controller (PLC) panels, providing compact and reliable control for automated processes and machinery.

### **Electrical & Electronic Systems**

Rocker switches are essential components in various electrical and electronic systems, ensuring safe and reliable operation, such as:

- **Power Distribution Panels:** IP67 rocker switches and IP65 rocker switches are used in power distribution panels to control circuits, isolate power sources, and provide protection against [electrical hazards](https://sg.rs-online.com/web/content/discovery/ideas-and-advice/industrial-electrical-safety-guide) in demanding environments.
- **UPS Systems:** Rocker switches are used in uninterruptible power supply (UPS) systems to switch between different power sources, ensuring continuous power supply to critical equipment in case of power outages.
- **Server Racks:** Rocker switches are commonly found in server racks to control power to individual servers, network devices, and other components, providing convenient access and management of power distribution.

### **Automotive & Transportation**

Rocker switches are widely used in the automotive and transportation industry to control various functions within vehicles and other modes of transport, such as:

- **Vehicle Dashboard:** Illuminated rocker switches and LED rocker switches are commonly used in vehicle dashboards to control lights, wipers, climate control, and other accessories, providing clear visibility and ease of use for drivers.
- **Heavy Machinery:** Rocker switches are used in heavy machinery, such as construction equipment and agricultural vehicles, to control various functions, including engine start/stop, hydraulic systems, and lighting.
- **Aircraft:** Rocker switches are used in aircraft cockpits and control panels to control various systems, including lighting, navigation, and communication, ensuring reliable operation in critical aviation environments.
