GVP has been manufacturing high-quality, durable membrane switches for the medical device, military, automotive, marine, and OEM industries since 1973. Membrane Switches in Minneapolis MN

What is a Membrane Switch?

Membrane switches are part of the user interface for an electronic device. They are typically used to communicate a user’s command to the device, turning it on or off. The circuit actuation is performed by pressing a specific location on the user interface (such as a key), thus closing the circuit within the printed electronics below. When the membrane switch key is released, the circuit poles separate, and the circuit returns back to an open state. Membrane Switches in Minneapolis MN

A common membrane switch construction is made of a thin film layer of polyester. This type of film is used in many products because it can be easily manufactured and it’s chemically resistant. The circuitry is made using a series of printed conductive inks; this makes it different from copper-etched printed circuit boards (PCBs). Membrane switches cost less than copper-etched PCBs, and they also take less time and money to develop. Membrane switches can be made with different types of actuation. These include non-tactile flat keys, metal domes for a tactile and audible response, Polyester formed domes as well as capacitive options. Other electronic components can be mounted into a Membrane Switch as well for added functionality. Low profile LEDs, resistors, and capacitors can be integrated into the circuit construction providing more enhanced user feedback options.

• Retail and consumer-related equipment or machines (i.e., exercise equipment, vending machines, gasoline pumps, etc.)

Key Benefits for a Membrane Switch:

Customized User Interface Options:

As our Membrane Switches are custom built to your specifications, you can tailor the interface to meet your specific needs.

Custom Graphics:

Membrane switches can be customized with a wide range of graphic options, including custom logos, textures and multi-color specialized graphics.

Reduced Footprint:

Low profile construction provides a space-saving design option.

Moisture Resistance:

We can provide a fully sealed construction that can hold up to an IP65 rating by using a gasket or drop-in switch construction.

Easy to Replace:

The Membrane Switch is a surface-laminated component that provides a faster, low-cost replacement for field and refurbish applications. Since the Membrane Switch is all contained in one package, it provides a drop-in place option without the costly replacement of circuit boards inside the unit.

Lower Cost and Lead Time:

When compared to copper etched flex circuits and printed circuit boards (PCBs), a Membrane Switch offers a greater cost reduction in the form of lower upfront tooling costs and shorter lead time.
