Environmentally Sealed Membrane Switches Made to Survive When Reliability is Critical
A membrane switch (man machine interface) is made by screen printing conductive inks in a specifically designed pattern onto a heat stabilized polyester substrate. A graphic is added to the circuit using adhesive. When a button is pressed it makes a connection with the circuit thereby communicating with the equipment or device.
Membrane switches have long been the industry standard for user interface among a wide range of industries.
Applying HeatSeal® technology to our high quality membrane switches allows them to operate in environments where pressure sensitive adhesive (PSA) switches often fail. Plus, every part is 100% tested to ensure quality you can trust.
Membrane Switches Designed to Last
At the design stage, not every environmental condition under which the membrane switch will operate is known. Something as common as a spilled beverage in an office environment can disable a PSA switch, but HeatSeal® protects from contaminants like this. HeatSeal® automatically incorporates safeguards in the design.
Telamco’s affiliation with The Bergquist Company enables us to offer HeatSeal® technology to low and mid-volume membrane switch users. HeatSeal® is a registered trademark of The Bergquist Company.
Telamco proudly manufactures membrane switches that can be found in products in a variety of industries.
The materials and processes used in the fabrication of HeatSeal® produces a true hermetically sealed switch. The adhesive bond produced in the HeatSeal® process is superior to that of PSA construction found in other membrane switches. The HeatSeal® bond effectively seals out harmful environmental contaminants that can cause failure in standard PSA switches.
Because air neither enters nor escapes a HeatSeal® switch external venting is not required even when subjected to changes in temperature or atmospheric pressure.
