Key Features
1. Smallest Footprint on the Market – No Compromise on Space Design:
As the smallest pushbutton switch currently available, the 8U series redefines miniaturization standards with its extremely compact package dimensions. For PLC modules, GPS terminals, automotive ECUs, and portable medical devices where internal space is measured in millimeters, the 8U series makes reliable switching a reality even on an area the size of a fingernail. Through precise structural optimization, our R&D team has achieved both functional completeness and mechanical stability within the smallest possible volume.
2. IP67 Fully Sealed – Even a Micro Switch Can "Dive":
Breaking through the industry bottleneck in protective performance for miniature switches, the 8U series achieves one of the highest IP67 ratings. It completely prevents dust ingress and withstands temporary immersion in water up to 1 meter deep for 30 minutes. The rubber sealing structure, rigorously verified by our quality assurance team, ensures that the seal maintains its elastic recovery under long‑term compression and thermal cycling – without aging or leakage. This feature enables the 8U series to be used for the first time in outdoor, humid, and high‑dust environments.
3. Dual Orientations and Dual Angles – Maximized Layout Flexibility:
Actuator Orientations: Vertical (push‑in) and horizontal (side‑actuated)
Terminal Angles: 90° bent and 180° straight
These four combinations cover all installation scenarios – from standard PCBs to ultra‑thin devices, and from front panels to side frames. The side‑actuated version fits device side panels just millimeters thick, while the 90° bent terminals accommodate horizontal routing on high‑density multi‑layer PCBs – freeing mechanical designers from compromising overall layout due to switch orientation.
4. Dual Circuit Topologies – Full Signal Switching Coverage:
SPDT: Single‑pole double‑throw – basic switching function.
DPDT: Double‑pole double‑throw – synchronous dual‑circuit control.
Both circuit configurations share the same miniature package, enabling the 8U series to cover the vast majority of design requirements – from simple on‑off switching to complex multi‑circuit selection – greatly simplifying BOM management and supply chain complexity.
5. Gold‑Plated Contacts with Nickel Barrier – Pristine Micro‑Power Signals:
Contacts are made of phosphor bronze substrate, plated with a nickel barrier layer followed by a gold overlay. The nickel layer effectively prevents copper ion migration to the gold surface, while the gold layer provides extremely low contact resistance and excellent chemical stability. This dual protection ensures that the contacts maintain stable operation with ultra‑low resistance of ≤100mΩ over the long term. For precision signal circuits at the 0.4VA level, this process completely eliminates intermittent failures caused by oxidation in "dry circuit" applications.
Applications
PLC Control Modules:
Input/output channel manual triggering, address DIP switch settings, and mode configuration – the ultra‑compact size fits compact PLC expansion modules.
GPS Navigation Terminals:
Positioning mode switching, emergency call triggering, and function confirmation keys – IP67 protection adapts to in‑vehicle and outdoor environments.
Automotive Electronics:
Function configuration on on‑board ECUs, diagnostic interface triggering, and test keys for body control modules – ‑40°C low‑temperature start‑up ensures reliable operation in frigid regions.
Small Test & Measurement Instruments:
Oscilloscope trigger buttons, multimeter function selection, and data acquisition system mode switching – gold‑plated contacts ensure pure measurement signals.
Medical Equipment:
Function keys on portable patient monitors, confirmation keys on mobile ultrasound devices, and mode selection on rehabilitation equipment – the rubber sealing meets cleaning and disinfection requirements.
Network & Communication Equipment:
Router reset buttons, switch configuration keys, and test interfaces on fiber optic terminal boxes – DPDT enables simultaneous dual‑channel switching.
