Product Overview
The BTE Series is an ultra‑miniature detection switch designed for precision electronic equipment, built around the product philosophy of "miniature to the millimeter, imperceptible yet responsive." Featuring an extremely slim profile, the switch achieves an operating life of up to 100,000 cycles and an ultra‑light actuation force of ≤50 gf within a precision signal‑level power rating of just 1mA / 5VDC. Its optional positioning pin design provides assembly engineers with an intuitive orientation guide, completely eliminating the risk of incorrect direction during SMT placement or hand soldering. The entire series is manufactured with halogen‑free environmentally friendly materials, preventing the release of hazardous substances at the source – making it an ideal fit for cutting‑edge electronics applications such as notebook computers, smartphones, and sensor modules, where space, environmental compliance, and reliability are paramount.

Key Features
1. Ultra‑Low Profile Design – Maximizing Space Utilization:
Ranking among the thinnest in the detection switch category, the BTE series' ultra‑slim package allows it to be easily embedded into extreme space‑constrained scenarios – such as notebook computer hinges, smartphone side‑button assemblies, and sensor module housings. For consumer electronics that pursue "millimeter‑thin" designs, the BTE series is a key component for achieving high‑level internal integration.
2. Optional Positioning Pin – Zero Assembly Errors:
Available in two versions: with or without a positioning pin.
With Positioning Pin: A locating hole on the PCB automatically aligns the switch to the correct soldering orientation upon insertion, eliminating the risk of 180° reverse‑placement that could result in entire batch scrappage.
Without Positioning Pin: Suited for high‑density PCB layouts, avoiding conflicts between the pin and surrounding traces or components.
This design boosts assembly tolerance to near 100%, significantly reducing rework rates and inspection costs on SMT production lines.
3. Halogen‑Free Materials – A Pioneer in Green Electronics:
The entire series is manufactured with halogen‑free materials, which do not release toxic corrosive gases such as hydrogen chloride or hydrogen bromide under combustion or high‑temperature conditions. This is particularly critical for electronic devices in enclosed spaces (e.g., inside notebook computers and smartphone bodies), protecting end‑user health while meeting the compliance requirements of EU RoHS, REACH, and major global environmental regulations.
4. Micro‑Amp Precision Contacts – Pristine Signal Integrity:
Rated at 1mA / 5VDC, optimized for micro‑power applications such as digital signal detection, status feedback, and position sensing. With contact resistance ≤2Ω, signal attenuation at milli‑amp levels is negligible. Gold‑plated or special‑alloy contact processes ensure long‑term contact stability, preventing intermittent failures caused by oxidation in "dry circuit" applications.
5. Light Actuation Force – Delicate and Responsive Tactile Feel:
With a maximum actuation force of 50gf and a precise travel of approximately 1.03mm, the BTE series delivers a "light‑touch, instant‑response" feel. For frequent‑opening applications like notebook hinge detection and smartphone side‑key travel sensing, the light actuation force not only extends mechanical life but also enhances the end‑user's interaction experience.
Applications
Laptops: Screen hinge open/close detection, keyboard backlight triggering, trackpad press recognition, and cooling fan cover status monitoring – the ultra‑low profile design adapts to the extreme internal space of ultra‑thin notebooks.
Smartphones: Side volume/power button stroke detection, SIM card tray insertion recognition, flip cover open/close sensing, and camera module升降 (pop‑up) position feedback – the positioning pin ensures zero‑error SMT high‑speed placement.
Sensor Modules: Micro‑switch triggering for door/window magnetic contacts, liquid level float position detection, angle sensor limit position recognition, and pressure sensor calibration contacts – the 1mA precision contacts ensure distortion‑free weak signal transmission.
Wearable Devices: Smartwatch crown press detection, TWS earphone charging case open/close recognition, and health monitoring device button triggering – halogen‑free materials provide added safety for close‑to‑skin use.
IoT Terminals: Smart door lock handle position detection, smart home panel touch feedback, and industrial sensor status switching – 100,000‑cycle life ensures long‑term stable equipment operation.
