Sports Watch Dome Sheet Array

Our sports watch dome sheet array is a practical, ready-to-install button switch component for all types of smart sports watches. Made of durable SUS301 stainless steel domes and high-viscosity PET adhesive sheet, it delivers crisp, consistent button clicks in daily sports and outdoor scenarios. Sweat-proof, ultra-thin and fully customizable, it fits most watch PCB and FPC boards for mass production.

Overview

Sports watches are always used in complex environments. Sweat, frequent shaking, temperature changes and repeated pressing will easily cause ordinary watch buttons to fail, such as unresponsive clicks, fuzzy touch and poor sensitivity. This directly affects user experience and product service life.

Yo-Shan specializes in manufacturing dome sheet arrays for wearable watch buttons. Different from scattered single metal domes that require manual placement, our products are pre-arranged and fixed on integrated PET sheets. Factory teams can complete one-time lamination mounting, which greatly simplifies the assembly process, improves product yield and saves production costs.

Widely applied in fitness watches, outdoor rugged watches and waterproof sports trackers, our dome sheet arrays have always been trusted by wearable device manufacturers for stable performance and low failure rate.

How It Works

The working principle of the watch dome sheet array is simple and reliable. Each precision-formed metal dome is fixed at a standard position on the PET adhesive layer. When users press the watch side button, the dome is stressed and sinks down to contact the circuit board pad, turning on the circuit and realizing signal triggering.

After releasing the pressure, the stainless steel dome rebounds quickly and cuts off the circuit. The whole pressing and rebounding process brings clear tactile feedback. It supports long-term frequent use without extra silicone keypad assistance, suitable for ultra-thin watch internal structural design.

Product Features & Advantages

Stable Tactile Pressing Experience We offer 100g, 120g, 140g and 160g actuation force options to meet different watch design needs. All products are strictly controlled in terms of force, stroke and rebound tolerance. Each batch maintains consistent pressing feel, effectively avoiding hard pressing or accidental false touch during sports movement.

Strong Sweat & Corrosion Resistance Adopting high-fatigue SUS301 spring stainless steel raw material, the domes support nickel plating, silver plating and gold plating surface treatment. Gold-plated domes perform excellently in sweat and humid environments, effectively resisting corrosion and oxidation, perfectly matching swimming watches and high-frequency fitness sports watches with long service life requirements.

Ultra-Thin Design for Lightweight Watches The integrated sheet structure occupies very little internal space of the watch. It solves the space limitation problem of slim sports watch shells. The saved internal space can be used for larger batteries and various sensor modules, helping brands improve watch battery life and sports monitoring functions without increasing body thickness.

High Production Efficiency & High Yield All metal domes are positioned accurately on the PET sheet with unified standards. Batch lamination assembly can be realized on the production line, reducing manual placement errors and improving overall production efficiency. Every product will pass conductivity test, tactile detection and fatigue life test before delivery to ensure stable mass delivery quality.

Flexible Customization Service We support personalized customization according to customers' PCB and FPC drawings. You can adjust the number of domes, spacing, layout shape, pressing force and surface plating process. We support both small-batch prototype sampling for R&D testing and large-batch mass production orders, fully meeting the differentiated needs of smart watch projects.

Technical Specifications

Application Range

Our sports watch dome sheet arrays are widely used in all kinds of wearable smart devices. The main applicable products include outdoor sports smart watches, daily fitness tracker watches, waterproof swimming sports watches, rugged outdoor wear-resistant watches and children's sports smart watches. It is a cost-effective and high-stability button switch accessory for wearable consumer electronics.

Selection Guide

Most daily fitness smart watches are suitable for 120g-140g actuation force, which balances comfortable pressing and anti-mis-touch effect. Lightweight mini sports watches can choose 100g low-force domes for more flexible operation. For outdoor adventure and heavy-duty sports watches, 160g high-force domes are recommended to avoid accidental touch failure during strenuous exercise.

In terms of surface process, nickel-plated domes are cost-effective for conventional indoor sports watches. For waterproof, sweat-resistant and long-life watch models, gold-plated dome sheet arrays are preferred for more stable conductive performance and stronger corrosion resistance.
