King Epoxy Emblem Co., Ltd » Membrane Switches

Custom Membrane Switches & Capacitive Switch Manufacturer

Your reliable Membrane Switch Manufacturer.

Custom Membrane Switches for Every Application

King Epoxy Emblem is a custom membrane switches manufacturer, building membrane switches manufacturers rely on for security keypads, cell phone touch screens, aircraft control panels, airport kiosks, personal gaming devices, tablets, home appliances, and more. Provide us with your specifications, and our team will design a capacitive membrane switch optimized for your application.

Membrane Switch Construction & Layers

We craft our membrane switch bases using polymer thick film (PTF). Typically, our membrane switches feature a single conductor layer structure. However, we also frequently manufacture membrane switches with two or more metal insulating layers, including



A graphic layer for screen-printed decorations or graphics such as numbers and letters.



A tactile layer that provides a tactile effect, simulating the sensation of pushing a button.



A rigid metal layer that supports a flexible static layer as a backing.

Frequently Asked Questions

Q1: What is the difference between a standard and capacitive membrane switch?

A: A standard membrane switch uses mechanical contact between conductive layers, while a capacitive membrane switch senses touch electronically — similar to a smartphone screen — and activates with a light touch, without requiring physical contact between layers.

Q2: What industries use custom membrane switches?

A: Custom membrane switches are used in security keypads, medical devices, aircraft control panels, airport kiosks, gaming devices, tablets, and home appliances.

Q3: Can membrane switches include backlighting or LED indicators?

A: Yes. King Epoxy Emblem builds membrane switches with embedded surface-mount LEDs and backlighting using light guide films.

Q4: Are your membrane switches water- and dust-sealed?

A: Yes. King Epoxy Emblem offers water-sealing and ESD/EMI shielding options to protect membrane switches in demanding environments.

Q5: What is polymer thick film (PTF) and why is it used in membrane switches?

A: Polymer thick film is a printed conductive ink used to form the circuit layer of a membrane switch. It is durable, cost-effective, and allows for thin, flexible switch assemblies.
