Product Overview
The G9 Series is a sealed miniature micro switch engineered to meet the dual demands of compact space and harsh environments. Despite its extremely small footprint, it achieves IP67 dust‑tight and watertight protection – setting a benchmark as a "small yet tough" performer among similar miniature switches. A variety of plunger lengths and actuator styles, combined with a rich selection of terminal configurations, allow flexible adaptation to a wide range of applications, from automotive electronics to household appliances. Whether used for travel detection in car door locks, end‑position feedback for air‑conditioner louvers, or safety interlocking in food processors, the G9 Series delivers precise contact switching and outstanding sealing reliability, making it an indispensable critical component in precision control circuits.
Technical Parameters
Key Features
1. IP67 Fully Sealed Protection – Even a Micro Switch Can "Dive"
Breaking through the industry bottleneck in protective performance for miniature switches, the G9 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, enabling miniature switches to be used for the first time in outdoor, humid, and high‑dust environments.
2. Ultra‑Compact Design – Maximizing Space Utilization
With a miniature package occupying minimal PCB real estate, the G9 series provides critical support for the ongoing trend toward thinner, lighter, and more highly integrated electronic products. In space‑constrained automotive control modules and portable devices, the G9 series delivers maximum value in the smallest possible volume.
3. Two Current Ratings – Covering All Power Scenarios
P1 Rating: 0.1A @ 125/250VAC / 48VDC, optimized for low‑level applications such as signal detection and sensor loops.
05 Rating: UL certified 5A / ENEC certified 6A @ 125/250VAC, capable of power‑level applications like relay driving and motor control.
Both ratings share the same compact package, greatly increasing selection flexibility.
4. Wide Temperature Range up to +120°C – Withstanding High Heat
With an operating temperature range from ‑25°C to +120°C – far exceeding the conventional +85°C limit of ordinary micro switches – the G9 series is particularly well‑suited for high‑temperature environments such as automotive engine compartments, electric heating appliances, and industrial heat‑treatment equipment.
5. 500,000 Mechanical Cycles – Long‑Term Reliability
Featuring a mechanical life of up to 500,000 cycles and an electrical life of 10,000 cycles, the G9 series maintains stable contact switching performance even in frequent‑actuation scenarios, significantly reducing equipment maintenance frequency and after‑sales service costs.
