Product Overview
The 4B Series is a compact surface‑mount (SMT) rocker switch engineered specifically for harsh environments, combining miniaturized packaging with industrial‑grade protective performance. Featuring an IP67 dust‑tight and watertight rating, it withstands temporary immersion and dusty sealed enclosures, while delivering a rated current‑carrying capacity of up to 3A – demonstrating exceptional power‑handling capability among similar SMT switches. The actuator cap supports customized status markings such as "OI", allowing operators to clearly identify the on/off state at a glance even under complex working conditions. From outdoor communication base stations to precision test instruments, the 4B Series embodies the design philosophy of "small size, big performance", offering engineers an ideal switching solution that balances automated assembly, environmental adaptability, and electrical reliability.
Technical Parameters
Key Features
1. IP67 Fully Sealed Protection – Withstands Harsh Environments
Meeting the IP67 standard, one of the highest ingress protection ratings, the switch completely prevents dust ingress and can withstand temporary immersion in water up to 1 meter deep for 30 minutes. This allows direct deployment in outdoor equipment, humid workshops, and high‑dust industrial sites without the need for additional protective covers.
2. SMT Package – Ready for Smart Manufacturing
Designed with surface‑mount technology, the 4B series is fully compatible with modern high‑speed SMT production lines and supports automated reflow soldering. This significantly improves assembly efficiency and solder joint consistency, while reducing manual insertion costs and PCB through‑hole occupancy – helping products become thinner, lighter, and more highly integrated.
3. 3A High Current Capacity – Small Size, Big Power
Achieving a 3A rated current (resistive load @ 120VAC/28VDC) within a compact SMT package, this switch breaks the traditional limitation that SMT switches are only suitable for signal‑level switching. It can directly drive medium‑power loads such as relay coils, small motors, and LED modules, reducing circuit stages and optimizing BOM cost.
4. 50,000 Mechanical Cycles – Built to Last
With a mechanical life of up to 50,000 switching cycles, this switch far outlasts ordinary consumer‑grade alternatives, ensuring that equipment does not require frequent maintenance or replacement over its entire service life, thereby lowering after‑sales service costs.
5. Intuitive Status Indication – Zero Misoperation
The actuator cap can be laser‑marked with "OI" (ON/OFF) or other custom symbols, providing clear visual feedback in combination with the toggle direction. This effectively prevents operational errors and enhances equipment safety.
