Product Overview
The 4A Series is a sealed sub‑miniature rocker switch engineered for harsh environments and high‑density installations. Combining IP67‑rated full sealing protection with an impressive 3A current‑carrying capacity in an ultra‑compact footprint, it pushes the application boundaries of miniature rocker switches beyond dry indoor settings to demanding conditions involving moisture, dust, and outdoor exposure. The black nylon actuator incorporates an integral O‑ring seal, while the glass‑filled nylon 6/6 base is UL 94 V‑0 flame‑retardant certified—every detail is designed to ensure reliable on/off performance in adverse environments. Whether enduring the elements at outdoor communication base stations or withstanding frequent operation on precision test equipment, the 4A Series delivers clear‑at‑a‑glance and rock‑solid power and signal control through the distinct raised and lowered positions of its rocker ends.
Technical Parameters
Key Features：
1. IP67 full sealing protection – impervious to dust and moisture：
Precision O‑ring sealing and an integrated waterproof design achieve the highest IP67 protection rating, completely blocking dust ingress and withstanding temporary immersion. Rain, water spray, high‑pressure washing, and humid salt‑fog environments—no matter the conditions, the internal contacts remain dry and pristine, with switching performance unaffected.
2. SPDT/DPDT dual configurations – flexible single‑pole or double‑pole control：
Available in both SPDT and DPDT circuit forms, accommodating single‑circuit signal switching or dual‑circuit synchronous control as needed. The precision contact system ensures synchronized, stable switching across every circuit with minimal crosstalk, meeting diverse requirements from simple power switches to complex signal routing.
3. OI status marking – ON/OFF at a glance：
The actuator cap can be silk‑screened with "O/I" power symbols (O = OFF, I = ON), while the rocker's tilt angle intuitively indicates the circuit state. Whether in dimly lit cabinet interiors or under intense outdoor sunlight, operators can confirm the switch status with a single glance, enhancing operational safety and maintenance efficiency.
4. ‑40°C to 85°C wide temperature range – unfazed by extreme heat or cold：
From minus forty degrees in northern winters to scorching summer heat on industrial sites, the 4A Series maintains consistent mechanical feel and electrical performance. The glass‑filled nylon base and weather‑resistant sealing materials ensure no deformation, aging, or leakage under extreme temperatures.
5. 30,000‑cycle mechanical life – built to last：
The optimized spring‑rocker mechanism and wear‑resistant contact design deliver a mechanical life of 30,000 switching cycles. Whether in frequently operated test equipment or long‑running communication base stations, it consistently provides crisp, positive tactile feedback—no sticking, no loosening.
