Structure of Seesaw Switch/Rocker Switch

Operation button

This button is manually pressed to switch between ON and OFF.

Sealing rubber

A component used to seal the switch. It prevents moisture and foreign objects from entering the internal case.

Semi-elliptical spring

It has a contact attached to the end. When the operation button is ON, it moves the contact to a fixed one. Then, it exerts high contact force for a stable connection between the two. But when it is OFF, the release contact force is increased, preventing contact welding.

Internal case and lid

The components that make up the switch mechanism. Terminals, contacts and semi-elliptical springs are stored in the case and the lid as a seal.

Cover

A resin component that covers the sealed internal case. It is also used to secure the sealing rubber into place. Moreover, it allows the switch to be easily mounted into a square hole in a panel.

Contacts and terminals

The fixed contact is made by attaching a contact to the end of one of the terminals.

FAQ

Q: What is a seesaw switch (rocker switch)?

A: A seesaw switch, also known as a rocker switch, is an electrical control device that rocks back and forth to open or close a circuit, enabling control of vehicle accessories, lighting systems, and other electrical devices.

Q: What types of seesaw switches are available?

A: Common types include single-pole single-throw (SPST), single-pole double-throw (SPDT), illuminated, non-illuminated, waterproof, and heavy-duty switches, each designed for specific applications and load requirements.

Q: What is the difference between a seesaw switch and a push-button switch?

A: A seesaw switch maintains its position until manually changed, while a push-button switch typically returns to its original position after activation (momentary). This makes rocker switches ideal for continuous control applications.

Q: Where are seesaw switches commonly used?

A: They are widely used in automotive dashboards, marine panels, industrial equipment, power tools, and household electrical devices where reliable on/off control is required.

Q: What voltage and current ratings are typical for seesaw switches?

A: Most automotive and industrial rocker switches are rated for 12V or 24V DC systems, with current ratings ranging from 5A to 30A depending on the application. Higher-capacity switches are available for heavy-duty equipment.

Q: Are seesaw switches waterproof?

A: Many models are designed with IP65 or higher protection, making them resistant to water, dust, and debris. This feature is particularly important for off-road vehicles, boats, and outdoor industrial equipment.

Q: Can seesaw switches handle high-power devices?

A: While standard switches can handle moderate loads, high-power devices are usually controlled via a relay. The switch activates the relay, which then carries the high current safely.

Q: What materials are used in high-quality seesaw switches?

A: Durable switches often feature thermoplastic or nylon housings, metal alloy contacts, and corrosion-resistant terminals to withstand vibration, temperature extremes, and repeated use.

Q: How do illuminated rocker switches work?

A: Illuminated switches contain a built-in LED or indicator that lights up when the switch is active. This improves visibility in low-light conditions and provides clear operational feedback.

Q: How can I ensure compatibility with my system?

A: Check voltage, current rating, terminal type, and mounting dimensions. For specialized applications, verify IP rating, illumination type, and whether the switch is designed for DC or AC systems.

Q: What is the typical lifespan of a seesaw switch?

A: High-quality switches are rated for tens of thousands of cycles under normal conditions. Lifespan depends on electrical load, environmental conditions, and usage frequency.

Q: Can seesaw switches be customized?

A: Yes. Many manufacturers offer OEM/ODM services, including custom colors, labeling, illumination, voltage ratings, and actuator shapes to match specific vehicle dashboards or industrial panels.

Q: How should seesaw switches be installed?

A: Installation usually involves securing the switch in a compatible panel opening and connecting the terminals according to the wiring diagram. Proper insulation and torque on fasteners ensure safe and reliable operation.

Q: Are seesaw switches suitable for both automotive and marine applications?

A: Yes, provided the correct IP rating, corrosion-resistant materials, and voltage rating are selected. Waterproof models with robust terminals are preferred for marine environments.

Q: What should distributors consider when sourcing seesaw switches?

A: Distributors should evaluate durability, IP rating, electrical specifications, compliance with safety standards, and manufacturing consistency. Suppliers offering quality testing, certifications, and reliable supply chains are preferred for B2B partnerships.
