Leading Rocker Switch Manufacturers

Types of Rocker Switches

Rocker switches are versatile, user-friendly electrical switches that are widely used across various industries and applications. Selecting the right rocker switch configuration is essential for ensuring safety, efficiency, and reliable electrical control within your system. Understanding the available types, their functions, and their ideal use cases can help you make informed purchase decisions when choosing rocker switches for your projects.

3-Position Configuration

Three-position rocker switches, often referred to as 3-way rocker switches, are designed to enable flexible control over electrical circuits. They feature three distinct electrical connections:

• The input power is delivered to the rocker switch at the pin.
• The device the switch will activate is linked to the pin.
• The switch is connected to the ground or is left unconnected at the pin.

This configuration allows users to toggle between two circuits or states, or to have a central 'off' or neutral position. 3-position rocker switches are commonly used in applications where an operator may need to control a device in two directions, such as in motorized window actuators or adjustable equipment controls.

Momentary Rocker Switch Configuration

Momentary rocker switches differ from standard maintained switches by only activating an electrical circuit while being pressed. When users press a standard rocker switch, it latches into that position and stays there until it is moved the other way. However, a momentary switch only activates when it is depressed and goes back to its normal setting when it is not. Typical applications include horn buttons, reset switches, or any device where a temporary electrical connection is needed for safe operation.

Maintained Rocker Switch Configuration

Maintained rocker switches have three positions—UP, DOWN, and sustaining—and operate similarly to an automobile window switch. This rocker switch style implies that internal limit switches will disconnect the power to the actuator once it has completed its full stroke. When the user presses the switch, it remains in that position. One only needs to depress the switch's down button to bring the actuator back. Maintained rocker switches are ideal for applications such as power windows, seat adjustments, and systems that require a stable, hands-free operation.

Rocker Switch Components

Rocker switches are complex devices consisting of various yet critical parts. Understanding these components is essential when evaluating rocker switch quality, durability, and suitability for different electrical and electronic applications.

Operation Button

The operation button, or actuator, is the interface that users manually press or toggle to change the state of the switch. Many modern rocker switches feature illuminated buttons, tactile feedback, or labeling to indicate ON/OFF status, which improves usability and safety in low-light or high-vibration environments. Choosing the right actuator style can help optimize your control panel's ergonomics and accessibility.

Rubber Sealing

Rubber sealing is a rubber component used to seal the switch and protect it from moisture, dust, and other environmental contaminants. Weatherproof and waterproof rocker switches are essential in automotive, marine, and outdoor equipment to ensure long-term reliability, even in harsh conditions. If your application is exposed to the elements, consider IP-rated sealed rocker switches for maximum protection.

Spring and Contacts

The spring inside the switch is made by a leaf spring that has a contact attached at its end. When the switch is turned ON, the spring immediately advances its contact to another, fixed contact within the rocker switch unit. This connection of contacts provides electrical flow. However, this connection is broken as the spring retracts when switched back to the OFF position. High-quality contact materials such as silver or gold plating increase conductivity and reduce wear, ensuring a long service life and consistent performance in demanding industrial applications.

Cover

The switch's cover wraps around the interior casing to safeguard the rubber sealing and hold it in place. It also serves as a barrier against accidental activation and enhances the overall safety of the electrical circuit. Durable covers made from thermoplastics or polycarbonate materials offer additional impact and chemical resistance, making them suitable for rugged environments.

Terminals

Terminals must fix one of the contacts to ensure connection. This contact is linked to one of the terminal ends. Common terminal types include quick-connect, solder lug, screw, and PC (printed circuit) board pins, each offering unique advantages for different installation requirements. Selecting the right terminal configuration ensures reliable integration into your wiring harness or PCB assembly.

Configurations for Pole and Throw

Rocker switches are categorized by their pole and throw configuration, which defines how many circuits can be controlled and how many output paths are available. Understanding these options is crucial when designing control panels, machinery, or consumer electronics.

One conductor in a single branch circuit can be connected or disconnected using SPST (single-pole, single-throw) rocker switches. This sort of switch is referred to as a single-pole, single-throw switch and normally has two terminals. SPST switches are commonly used for simple ON/OFF control in lighting, power strips, and other basic electrical devices.

A single conductor can be connected to one of two additional single conductors using SPDT (single-pole, double-throw) rocker switches. Typically having three terminals, these switches are frequently used in pairs. Three-way switches are another name for SPDT switches. They are ideal for applications requiring alternate control, such as switching between two circuits or selecting between power sources.

Two source terminals are frequently connected to the corresponding output terminals using a double-pole, single-throw (DPST) switch, which has four terminals (but never to each other). DPST rocker switches make or break the connection between two circuit conductors in a single branch circuit. Normally, they have four terminals. These are often used for isolating both live and neutral connections in AC mains circuits for added safety.

Two wires can be connected to two different circuits using DPDT (double-pole, double-throw) rocker switches. They typically come in versions with momentary and sustained contacts and have six terminals. In their (normal) condition, the contacts of a normally open (NO) rocker switch are either open or unconnected. Conversely, contacts in a normally closed (NC) rocker switch are closed or connected when they are in their (normal) condition. DPDT switches are ideal for reversing polarity in motors, switching between multiple devices, or complex control circuits.

Switch Functions

Rocker switches are available in multiple functional configurations to suit a wide variety of electrical control needs:

• Momentary ON: When the rocker switch is in the typical, open (NO) position, it depicts connections that break the circuit. This function is often used for push-to-activate devices such as buzzers, alarms, or motor starters.
• Momentary OFF: When the rocker switch is in the typical, closed (NC) position, describes connections that create a circuit. This is suited for safety interlocks or circuits that should remain energized except during manual interruption.
• Momentary center-NEUTRAL: Rocker switches with three positions feature an OFF or NEUTRAL function in the middle, offering flexible control for bidirectional motors or dual-mode devices.

When choosing a rocker switch, consider the intended function (ON/OFF, momentary, maintained, illuminated, etc.) and ensure compatibility with your application requirements.
