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.

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.

Rocker switches are commonly used in various applications, and people often have questions about them. Here are five of the most popular FAQs for rocker switches:
A rocker switch is an electrical switch that is actuated by pressing one end of a lever to make it tilt and create a connection or break it to disconnect. It typically has two positions: on (closed circuit) and off (open circuit). Rocker switches are commonly used for controlling lights, appliances, and other electrical devices.
Rocker switches come in various types, including single-pole single-throw (SPST), single-pole double-throw (SPDT), double-pole single-throw (DPST), and double-pole double-throw (DPDT). SPST switches have a single circuit, while SPDT switches can control two circuits with one actuator. DPST and DPDT switches offer two or four circuits, respectively. Additionally, there are momentary rocker switches that only maintain their position while they are pressed.
Wiring a rocker switch can vary depending on the specific type and application, but generally, it involves connecting the switch to the power source, load, and ground. Always consult the manufacturer’s instructions or an electrician if you’re unsure about the wiring, as incorrect wiring can be dangerous.
Yes, many rocker switches are suitable for both AC (alternating current) and DC (direct current) applications. However, it’s essential to check the switch’s specifications to ensure it’s rated for the voltage and current of your specific application. Using a switch rated for a lower voltage or current could lead to damage or safety issues.
Rocker switches are versatile and can be used in various applications, including controlling lights in homes and vehicles, operating appliances, turning on/off power tools, and managing electronic devices. They are often found in automotive panels, boats, and household electrical circuits. Rocker switches are chosen for their ease of use and durability.
