Silicone membrane switches with backlighting technology are not just ordinary switches. They are a blend of savvy engineering and smart technology, designed to deliver optimal user interface and experience. These switches find extensive application across various industries, including the marine sector. But before diving into their maritime usage, particularly in GPS devices, let’s understand the core mechanism that drives these switches.

The Core Mechanism

Backlit silicone membrane switches operate on a simple yet effective mechanism. They incorporate a thin, flexible membrane layer over a rigid back panel. When pressure is applied to the membrane, it makes contact with the circuit beneath, completing the electrical loop and initiating the designated action. The backlighting feature is ingeniously embedded within the membrane to ensure visual clarity, especially in low-light conditions.

Benefits of Backlit Silicone Membrane Switches


One of the core advantages is their durability. Being made from silicone, these switches are resilient to harsh conditions and prolonged use, making them ideal for outdoor applications.

Visual Clarity

The backlighting feature provides excellent visual clarity, allowing users to easily interact with the device, even in poorly lit environments.

User-Friendly Interface

Their soft yet tactile response offers a user-friendly interface, promoting ease of use and faster data entry, which is crucial in high-stakes environments like the maritime sector.

Weather Resistant

Being weather-resistant, they stand strong against the challenging marine conditions, protecting the internal circuits from moisture, salt, and other corrosive elements.

Usage in Marine GPS Devices

Enhancing Navigation

Marine GPS devices equipped with backlit silicone membrane switches facilitate seamless navigation. The backlighting feature ensures that the data on the GPS is clearly visible, irrespective of the ambient lighting conditions.

Safety in Adverse Conditions

In adverse conditions, having a reliable GPS device is paramount. The tactile feedback and backlighting feature of these switches ensure that the device remains functional and accessible, which in turn contributes to the safety of the marine personnel.

Day and Night Usability

The ability to operate the GPS device both during day and night without any hindrance is a significant advantage. The backlighting ensures that the GPS is usable even in the dark.

Data Entry and Control

Quick data entry and control are facilitated through a responsive interface, which is critical in emergency situations and during precise navigational adjustments.

Key Players in the Industry

Several reputable companies are at the forefront of designing and manufacturing backlit silicone membrane switches, contributing to the enhancement of marine GPS devices.

Installation Process

The installation process is straightforward, requiring minimal technical knowledge. Moreover, the compact design of these switches allows for easy integration into existing systems.

Future Advancements

With technology evolving at a rapid pace, future iterations of backlit silicone membrane switches are expected to bring about even more refined features enhancing usability and reliability in marine GPS devices.


Backlit silicone membrane switches have significantly upped the game in marine GPS technology, ensuring that navigation, safety, and control remain uncompromised even in the toughest of marine conditions.
