{"product_id":"4x4-matrix-membrane-keypad","title":"4x4 Matrix Membrane Keypad","description":"\u003cp\u003eThe 4x4 Matrix Membrane Keypad is a low-profile input device that provides 16 arranged keys in a compact, flat membrane format. It is designed for applications where a sealed, easy-to-clean, and cost-effective keypad is preferred over mechanical switches. The membrane construction yields a smooth surface and helps protect the underlying circuitry from dust and light moisture while maintaining reliable key activation.\u003c\/p\u003e\u003cp\u003eKey benefits include a compact footprint that simplifies panel integration, consistent tactile response suitable for repeated use, and straightforward electrical interfacing using a standard 4x4 matrix wiring scheme. The keypad is commonly used in prototyping, embedded control panels, access systems, consumer electronics, and industrial interfaces where a simple numeric or function matrix is required.\u003c\/p\u003e\u003cp\u003eInstallation is typically quick: the keypad can be mounted to a front panel or enclosure and connected to a controller using four row and four column lines. Its flat surface makes it simple to clean and resistant to snagging, and it can be paired with common microcontrollers and input-scanning libraries for rapid development. The membrane design also supports custom overlays and labeling for application-specific layouts.\u003c\/p\u003e\u003cp\u003eThis 4x4 Matrix Membrane Keypad offers a practical balance of durability, economy, and ease of use for projects and products that require a compact matrix input solution.\u003c\/p\u003e","brand":"Electronic Service Center","offers":[{"title":"Default Title","offer_id":45205211283639,"sku":null,"price":5.0,"currency_code":"LYD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/4010\/0279\/files\/IMG-6600.png?v=1756207762","url":"https:\/\/esclibya.com\/ar-ly\/products\/4x4-matrix-membrane-keypad","provider":"Electronic Service Center","version":"1.0","type":"link"}
