Membrane switches have become increasingly popular in recent years. As the name suggests, they feature a “membrane” design in which the circuit is printed on PET or ITO, typically using a conductive ink like copper, silver or graphite. Membrane switches are used extensively in human machine interfaces (HMI) and industrial equipment, offering a durable and reliable meats of operator input
So, why are membrane switches the preferred choice among so many business owners and professionals? One of the reasons for their widespread popularity is their waterproof design. Granted, not all membrane switches are waterproof, but many are. These waterproof models allow the membrane switch to be used indoors or outdoors, without fear of the switch succumbing to moisture-related damage.
A waterproof membrane switch typically has an airtight seal that’s resistant to even the smallest amounts of moisture. Whether it’s rain or humidity in the air, this seal forms of a barrier of protection between the membrane switch’s internal electrical components and moisture. Furthermore, the membrane switch will continue to operate even in the presence of moisture. This means workers may continue using the switch, regardless of whether or not it’s exposed to moisture.
Opting for a waterproof membrane switch typically increases its lifespan. Moisture can cause significant damage to switches, often to the point where it costs more to fix them that it does to replace them. If you choose a waterproof membrane switch, however, you can rest assured knowing it will withstand the hands of time for years to come, making it a smart investment. They typically cost more than non-waterproof switches, but it’s a small price to pay for the peace of mind knowing that water or moisture will not damage it.
Is a membrane switch the right choice for your business? There are both pros and cons associated with these switches. As noted above, the primary advantage of a membrane switch is its durable, waterproof properties, meaning you can use it outdoors. This alone is a huge benefit, as other switches typically lack waterproof characteristics. On the other hand, however, membrane switches have little-to-no tactile feedback, which can increase the chance of human error while subsequently reducing typing/input accuracy. In any case, membrane switches are an excellent choice for rugged and outdoor applications, as its internal electrical components are protected from moisture damage.
