Rocker Switches

A rocker switch operates by rocking back and forth. Rocking it one-way powers the circuit while pushing it the opposite way turns the circuit off. Known for their durability and ease of use, rocker switches are indispensable in modern electronics. We provide high-strength rocker switches from world-renowned manufacturers at discounted prices from the market.

Rocker Switches: Simple, Durable, and Essential

Rocker switches are among the most popular and common types of switches, and they can be found almost everywhere. A simple way to recognise a rocker switch is its rocking mechanism, which, when pushed, moves between two or sometimes more ways. When pressed, one side rises, and the other lowers down, resulting in making or breaking the circuit. 

Furthermore, they are not limited to just on/off functions; some types have three or more options to choose from according to requirements. However, switches with these features are more likely to be utilised in industrial-grade applications rather than domestic use.

How Do Rocker Switches Function?

Rocker Switches are typical electrical components that work by simply pushing or pressing downward one side of the switch to complete (turn on) the circuit. Additionally, breaking the circuit (turning it off) and putting a slight downward pressure on the other side can cause it to turn off. Typical rocker switches mainly perform two basic functions, such as:

• On Position: Pressing one end of the lever connects the electrical contacts and enables the current to flow to complete the circuit.
• Off Position: Applying a small amount of force on the other side disconnects the electrical contacts, preventing the current from flowing while interrupting the circuit.

What are the Available Rocker Switch Types?

Rocker switches come in a wide variety of sizes, formats, and styles, each offering numerous benefits and functionalities. Mostly used types include:

• On Off Switch 
• Double Rocker Switches
• 12V Switches
• Mini Rocker Switches
• Round Rockers
• 2 Way Rockers
• Round Rockers
• High Inrush Rockers 
• Power Rockers
• Momentary
• Pushbutton
• Changeover
• Centre-Off Switch

Let’s take a closer look at some of the most common types or styles mentioned above:

• On-off: They allow the user to choose between on and off points for power supply to one or more circuits concurrently. 
• Changeover: Also called a transfer switch, it is generally used to divert voltage to or transfer from one side of a circuit to the other.
• Momentary: These switches maintain their position after being pressed and stay engaged until manually switched back.
• Centre-off: They typically feature a central off point and come with at least two on points at either end of the see-sawing mechanism.
• Illuminated: Built-in LED for lamination to demonstrate whether a circuit is on or off.

Understanding Rocker Switch Poles and Throws

• Poles: The poles of a switch generally indicate the number of circuits the switch can make (complete/close/power) when it is turned on. 
• Throws: Throws, on the other hand, are the number of ON points the switch can move between to power/complete the circuits it is supervising.

Rocker switches are available in many different configurations, but the most common ones are outlined below:

• SPDT: Single Pole, Double Throw
• SPST: Single Pole, Single Throw
• DPST: Double Pole, Single Throw
• DPST: Double Pole, Double Throw

Where Can I Use Rocker Switches?

Rocker Switches can be seen in every aspect of our lives. They are typically found on wall sockets, extensions, power outlets and surge protection devices. Some of their typical applications include:

• Vehicle dashboards and electronics, defoggers, seat switches, and electric windows.
• Control Panels & Power Supplies
• Fuse Circuits
• Pneumatic & Hydraulic Systems
• HVAC Systems
• Healthcare Equipment
• Household Appliances, such as coffee makers, power stripes, vacuum cleaners, dehumidifiers and surge protectors.

Overall

Rocker switches are integral electrical components that provide usability, versatility, and durability in various applications. They are the fundamental components of modern electrical circuitry, powering various machines or equipment with a tiny footprint.
