Harsh Environment Membrane Switch
here are several elements and environmental conditions that can cause potential problems for Membrane Switch technologies, including:
Outdoor exposure to sunlight and UV rays
Exposure to harsh chemicals and/or solvents
Operator (mechanical) abuse
Dust and debris, often a problem for devices used outdoors
Extreme humidity
Extreme temperatures, both hot and cold
Atmospheric pressure at high altitudes
Moisture ingress
For this reason it is essential that your membrane switch supplier offer creative solutions to these challenges, both through unique switching technologies such as:
Dynapic Piezoelectric keypads and
DuraSwitch PushGate products.
Much of the process in designing membrane switch technologies for harsh environments involves selecting the appropriate materials and components to provide the protection necessary to ensure the integrity of each component within the membrane switch assembly.
The key considerations are choosing durable materials for the graphic overlay and selecting pressure-sensitive adhesives with the ability to withstand potential contaminants and other elements that could impact performance. A special adhesive sealing process can also be used to create an impervious bond that`s unaffected by the harsh conditions that would ordinarily cause device failure.
There are a range of options when it comes to durable materials and components capable of standing up in harsh, abusive, or rugged environments.
