SMD High Brightness Gold-Plated Metal Dome Membrane Switch With
IP67 Waterproof
An SMD (Surface Mount Device) membrane switch is a type of
waterproof, tactile user input component that is designed for
direct surface mounting onto a printed circuit board (PCB). Here's
a more detailed overview:
Construction
Utilizes a multi-layer membrane switch design:
Top graphic overlay - Provides branding, labeling, and visual
aesthetics
Flexible membrane - Acts as a waterproof and contaminant-resistant
barrier
Conductive switch elements - Printed circuit patterns that detect
button presses
PCB attachment layer - Allows for direct surface mounting onto the
circuit board
The entire assembly is typically quite thin, often less than 1mm in
total thickness
Mounting and Integration
The SMD membrane switch is designed to be directly soldered or
adhered onto the surface of a PCB
This enables a very compact, integrated solution where the switch
is an integral part of the electronic assembly
Can be automated into the PCB assembly process using standard SMT
(Surface Mount Technology) equipment
Applications
SMD membrane switches are commonly used in various compact,
waterproof, and rugged electronic devices, such as:
Handheld medical devices
Industrial automation and control panels
Automotive infotainment and control systems
Marine electronics
Consumer electronics and home appliances
