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, also known as membrane switch keypads, have long been the industry standard for user interface among a wide range of industries.
Applying HeatSeal® technology to our high quality electronic 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 electronic membrane switch will operate is known. Something as common as a spilled beverage in an office environment can disable a PSA switch or keypad, but HeatSeal® protects from contaminants like this. HeatSeal® automatically incorporates safeguards in the design.
Telamco proudly manufactures custom membrane switches that can be found in products in a variety of industries.
There are many associated components such as overlays, circuits, connectors, lighting and back panels that we can incorporate into your design. As an electrical membrane switch manufacturer, Telamco provides all of these components to provide a full-service product.
The materials and processes used in the fabrication of HeatSeal® produces a true hermetically sealed tactile switch/keypad. The adhesive bond produced in the HeatSeal® process is superior to that of PSA construction found in other electronic 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.
