Why are they so common? And how do they work? Here is everything you need to know about these switches and why they are so commonly used.

Advantages of membrane switches

Membrane switches are an excellent option for those looking for a long-lasting switch. They come in various colors and sizes to find the perfect one for your home or office. These are durable and reliable, making them a fantastic choice if you want something that will last. They come in many different shapes and sizes, which means there is a membrane switch for everyone.

Applications

Membrane switches are often used in automated and industrial environments because they are rugged and cost-effective. These switches have their roots in keyboard typing, which makes them an optimal solution for high-duty cycles. A membrane switch consists of a sealed, flexible diaphragm with electrodes embedded on the underside of the diaphragm, a printed circuit board (PCB) and the top cover seal. This design benefits machine guarding applications, easy actuation for sequential selections, and deficient operation force for extended life expectancy.

How membrane switches are used

These can be used in the following scenarios:

    Non-locking Rotary Selector Switch, where the operator must rotate until the desired position is found. This switch is typically for simplified applications, such as time and temperature display on wall-mounted dials.

    Lockable Rotary Selector Switch with detents, where an operator must rotate past one detent to confirm their selection before it locks into place. The different sections are mapped onto the number of notches past a detent that corresponds with the appropriate option. These are mainly used for industrial machinery and equipment, such as air conditioners and industrial control panels.

The advantages of using capacitive touch technology

Membrane switches are a type of capacitive touch technology. They are a popular choice for their convenience and reliability, quick response times, long lifespans, and excellent durability. Unlike resistive touch screens, which pass a current through two conductive layers of glass or plastic to identify your touch location, membrane switches use conductive properties in an air gap between the glass surface and metal switch membrane. This makes them more durable than their resistive counterparts because they don't rely on external power. It is impossible for dirt or oils from your fingers to break down their functionality. The only downside is that they need physical contact to work, so they won't be as easy to use in the winter months if you live somewhere cold.

Understanding how capacitive touch works

Membrane switches use a capacitive touch sensor which can detect changes in the proximity of a human finger as it approaches and recedes from the screen. The proximity of the user's hand on the screen creates an electrical field. This signal is detected by electrodes positioned underneath and inside the glass, usually on both sides of the touchscreen.
