Basically, a membrane keypad is a kind of special device for electronic sensitive touch. We use it for numeric input which even can work on low voltage with the help of a small PCB board. Moreover, a membrane keypad consists of a special backlit on its surface which completely covers its top area. Based on our high technology know-how, we fulfill your customer-specific requirements – from the simple touch point to the complete solution, in the highest quality and sophisticated design.

Certain materials can be heat resistant, meaning that they don’t warp or buckle in warm environments. Some materials and inks can deteriorate when left outside in the harmful sun rays. Engineers at Butler Technologies design many switches that do not degrade in sunlight or UV rays.

When the press released, the liên hệ of the upper circuit bounces back to cause the circuit disconnection, which triggers a signal. Due to the way they are constructed, membrane keypads provide a natural level of protection from dust and moisture ingress equivalent to IP54 standard, making them rugged, long lasting and easy to clean. This base level of protection can be further increased, subject to limitations, to enable units to have higher ratings up to a maximum of IP68 standard.

Membrane Panel

A membrane keypad is a keypad that contains a flexible tail with or without a connector according to the design & application. The keys of membrane keypads have multi layers of polymer also known as polyester sheets that are sandwiched together. Membrane keypads can be used in virtually any application that currently uses traditional mechanical switches. With the right specifications, a membrane switch assembly can even operate in extremely harsh environments.

Features and characteristics of this tail are not standard and are different in each project. The LEDs are the electronic component that allows illumination in the membrane keypad. CRESPO mounts SMD LEDs in different colors , bi-clour (Red / Green) or tri-colour (Red / Green / Blue). If your project does not include Metal Domes, it would not be necessary to include this layer in the structure of the membrane keypad. It includes all graphic design features to allow operating the keypad correctly. The Front Foil of the Membrane Switch is manufactured generally in Polyester or Polycarbonate.

A spacer in between two circuits which is die cut at liên hệ points. The die-cut holes allow the touch of a finger to close the contact, completing the circuit. The panel posterior is laminated with an adhesive for mounting to a backer or enclosure and is terminated with a means for interfacing with the customer’s electronics.

Many of our customers require custom keypads that must survive harsh conditions in the toughest of environments. And by utilizing some of our proprietary technologies and designs, our keypads can be built to last two million cycles and beyond. CSI Keyboards utilizes copper flex circuity and proprietary designs such as the Seal Frame and Life Extending Cushion to ensure your keypad is able to withstand and perform in extreme environments. Designed to evenly distribute light from top or side firing LEDs, providing bright, uniformed illumination. It also reduces the amount of LEDs needed, saving power consumption.
