FERLO TECH started in July 23, 1996, We have passed the auditing of ISO9001:2015 version QMS in DEC.3,2021.we have more than 20 years of expertise in industrial-grade Membrane Switch, design and production technology, and use our rich printing knowledge and experience to produce Membrane Switch, including overlay printing and circuit layout, Film forming, metaldome or polydome, as well as printed circuit… and other products.

The Membrane Switch , we provide include stable assembly of LEDs, resistors, photoreceptors and other components, as well as different requirements for waterproof, abrasion resistance, high temperature resistance, shock resistance and backlight, electrostatic protection, electric wave and high frequency interference and other protection designs. More dedicated to the environment protection. In the future, we will focus on making products lighter, buttons more sensitive, and a human-machine integrated(HMI) interface.
We are also good at solving client-side product related issues and determining the perfection of product functions is our important service orientation. The reputation of customers is the reputation of FERLO Technology.

Membrane switch is an operating system with key functions, indicating elements, and instrument panels. It consists of four parts: panel, upper circuit, isolation layer and lower circuit.
The principle of the membrane switch is as follows: Press the membrane switch, the contact of the upper circuit is deformed downward, and the pole plate of the lower circuit is contacted and conducted. After the finger is released, the contact of the upper circuit bounces back, the circuit is disconnected, and the circuit triggers a signal.

FERLO TECH is a professional design and manufacturer of human-machine interface (HMI). HMI is a general term used to describe the interface that enables you to interact with the machine. We provide the most advanced customized HMI products for the aerospace and military, industrial, medical, commercial and home appliance industries.

We use membrane switch, capacitive technology can be applied to panels of various thicknesses and materials, and the bonding technology between different thicknesses achieves a natural and easy control interface between humans and machines.

Our HMI components can be integrated into many applications, from customized R&D to design to assembly assembly. The industrial fields include home appliance control systems, sports treadmill equipment, communication systems, medical monitoring equipment and aerospace confidential precision equipment.















Conductive Rubber keypad is one of many electronic product keypad. Its main function is to achieve conductive buttons through conductive glue. When the conductive rubber button is pressed down, the conductive rubber of the button can be electrically connected with the contact below. When the silicone rubber button is released, the conductive rubber under the button springs up and will not communicate with the connection below. The conductive material of the conductive rubber key is a black conductive adhesive. When this conductive adhesive is added with a conductive filler, the conductive effect can be realized. Conductive rubber buttons need to consider the diameter, length, width and height of the rubber product, key stroke, pressing force requirements, product hardness, color, conductivity and other requirements.
