{"product_id":"4x3-matrix-membrane-keypad","title":"4x3 Matrix Membrane Keypad","description":"\u003cp\u003eThe 4x3 Matrix Membrane Keypad is a compact, low-profile input device configured in a 4 by 3 matrix layout to provide twelve keys for numeric and function entry. Its membrane construction delivers a smooth, sealed surface that minimizes dust accumulation and offers a flat form factor suitable for applications where space and durability are priorities.\u003c\/p\u003e\n\n\u003cp\u003eThis keypad arranges switches in a matrix to reduce the number of interface lines required between the keypad and a host controller, enabling simple microcontroller or PLC scanning routines. Typical uses include access control panels, point-of-sale terminals, consumer electronics, embedded control systems, and prototyping environments that require a straightforward numeric keypad with optional function keys.\u003c\/p\u003e\n\n\u003cp\u003eKey features and considerations:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e12-key 4x3 matrix layout for numeric input and common function keys.\u003c\/li\u003e\n  \u003cli\u003eMembrane construction provides a flat, easy-to-clean surface and compact profile.\u003c\/li\u003e\n  \u003cli\u003eMatrix wiring reduces I\/O lines and simplifies scanning in firmware.\u003c\/li\u003e\n  \u003cli\u003eSuitable for integration behind bezels or within housings where a low-profile user interface is needed.\u003c\/li\u003e\n  \u003cli\u003eInstallation requires matching the keypad matrix to the host input routine and ensuring correct mechanical retention in the target enclosure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eBecause membrane keypads vary by actuator style, contact method, and mounting provisions, verify compatibility with your system requirements and controller interface before installation.\u003c\/p\u003e","brand":"Electronic Service Center","offers":[{"title":"Default Title","offer_id":45205216034999,"sku":null,"price":5.0,"currency_code":"LYD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/4010\/0279\/files\/IMG-6602.png?v=1756207887","url":"https:\/\/esclibya.com\/en-ly\/products\/4x3-matrix-membrane-keypad","provider":"Electronic Service Center","version":"1.0","type":"link"}
