What is a Sub-mini Rocker Switch?
A sub-mini rocker switch, also known as a sub-miniature rocker switch, is a small-sized electrical switch that features a rocker-style actuator. These switches are designed for applications where space is limited, and a compact form factor is required. The “sub-mini” designation indicates that the switch is smaller than standard or miniature-sized switches.

Materials used for switches
For mini boat switch, because its volume is relatively smaller than other large switches, so whether it is plastic or metal materials we use more good materials, which can ensure that your application of the device is more secure and more have their own selling point.


Manufacturing process
To achieve the miniaturization of the miniature rocker switch, we utilize high-precision processing equipment to manufacture the related molds and accessories. This ensures consistency throughout the product production process and meets all your requirements for the product.
Key characteristics
These switches are significantly smaller than standard and even miniature-sized rocker switches, making them suitable for applications with limited space.
Similar to larger rocker switches, sub-mini rocker switches have a lever or paddle that can be rocked back and forth to open or close the electrical circuit.
Due to their small size, sub-mini rocker switches typically have a limited current-carrying capacity compared to larger switches. They are suitable for low to moderate current applications.
Designed for panel mounting, sub-mini rocker switches are commonly used in control panels, electronic devices, and other applications where space-saving is crucial.
Available in various configurations, including single-pole single-throw (SPST), single-pole double-throw (SPDT), double-pole single-throw (DPST), and double-pole double-throw (DPDT), providing flexibility for different applications.
Due to their small size, sub-mini rocker switches may have limited features compared to larger switches. They are typically basic on/off switches without additional functions.
Widely used in electronics, consumer appliances, automotive applications, and other devices where space constraints dictate the use of smaller components.
Sub-mini rocker switches often come with solder lug or quick connect terminals for easy installation.

Sub-mini Rocker Switch FAQs
Mini rocker switches are compact switches commonly used in various electronic applications. Here are some frequently asked questions about mini rocker switches:
A mini rocker switch is a small-sized switch that functions similarly to a standard rocker switch. It’s designed to fit into smaller spaces and is commonly used in electronics, automotive applications, and small appliances.
The size can vary, but generally, mini rocker switches are significantly smaller than standard ones. They are designed to fit into tight spaces where a standard switch would be too large.
They typically have solder lug, quick connect, or PCB mount connections. The type of connection depends on the specific model and its intended application.
While they are smaller and may not handle the same power levels as larger switches, many are still suitable for moderate power applications. Always check the voltage and current ratings to ensure they meet your needs.
Yes, many models come with built-in LED indicators or illumination for ease of use, especially in low-light conditions.
Installation typically involves mounting the switch in a cutout and connecting the terminals to your circuit. Always follow the manufacturer’s instructions for proper installation.
Some models are designed to be water-resistant or waterproof, making them suitable for outdoor or marine applications.
Yes, they are available in a variety of colors for both the switch body and the actuator (the part you press).
They are usually made from plastic, metal, or a combination of both, depending on the required durability and aesthetic.
It depends on the specifications of the switch, including its voltage and current rating. Always ensure the switch’s specifications match the requirements of your application.
