Custom Silicone Keypad with Dual-Stroke Switches for Electronic Keyboards

Product Overview

Shenzhen ES Electronic Co., Ltd. offers customized, high-end electronic keyboard solutions. In response to a client’s requirement, we upgraded a single-stage key mechanism to a dual-stage (dual-travel) design. By utilizing a dual-stage silicone structure with straight-walled columns, the mechanism provides distinct changes in resistance and tactile feedback during the pressing process. Accompanied by an audible "click" or vibration, this design helps users differentiate between a light press and a deep press, enhancing operational clarity and preventing accidental inputs.

Shenzhen ES Electronic Co., Ltd. provides custom dual-stage key solutions—including mechanical, capacitive, and optical/magnetic-sensing types. Leveraging the inherent elasticity of silicone, these keys offer stable rebound and a refined, comfortable tactile feel. We provide bespoke mold development tailored to the specific tactile preferences and lifespan requirements of each client’s product.

Shenzhen ES Electronic Co., Ltd.'s customized dual-stroke buttons meet IEC, ISO, and national standards. The first stage (light-press phase) involves a travel distance of 0.5mm–1.5mm with an actuation force of 20gf–50gf, while the second stage (deep-press phase) involves a travel distance of 1.5mm–3mm with an actuation force of 50gf–100gf.

Core Advantages

1.The multi-stage actuation design provides distinct tactile feedback; the clear resistance threshold between a light press and a deep press allows users to intuitively sense the actuation state. The silicone body offers excellent elasticity, while the slanted-wall compression structure ensures smooth rebound and uniform tactile response. This effectively addresses common issues found in traditional single-stroke buttons—such as difficulty in adjusting actuation force, poor rebound, and uneven keycap surfaces—ensuring that users do not confuse commands even during prolonged operation.

2.We offer a variety of dual-stroke button technologies—including mechanical, capacitive, and optical/magnetic-sensing types—allowing for selection based on specific requirements for cost, lifespan, and precision. These dual-stroke silicone buttons are constructed from temperature-resistant and moisture-proof materials with a stable structural design. They can be custom-engineered to meet diverse electrical standards and durability requirements, ranging from consumer electronics to industrial equipment.

3.Our proprietary dual-straight-wall silicone button design features inner and outer walls that are both perpendicular to the base substrate. The vertical distance between the base of the contact protrusion and the base substrate is 0.6 mm, enabling precise control over both the force-displacement curve and the actuation stroke.

Application & Custom Service

Dual-stage buttons are designed to meet the interaction requirements of a wide range of industries, including consumer electronics, smart home systems, automotive, industrial control, and precision medical equipment. Depending on the specific needs of each sector—such as requirements for tactile feel, operational lifespan, or precision—these buttons can be implemented using mechanical, capacitive, or optical/magnetic sensing technologies.

They are suitable for a variety of applications, such as camera shutters, game controllers, Bluetooth headsets, electronic keyboards, smart refrigerators, lighting control panels, automotive steering wheel buttons, industrial consoles, robotic arm controllers, and surgical control interfaces. By utilizing a two-stage actuation mechanism—a light press followed by a deeper press—these buttons enable diverse interactions, including function switching, parameter adjustment, and command confirmation.
