  • Nameplate, Membrane Touch Switch, and Graphic Overlays - HPA 1905 (.pdf)
    Designed for use on nameplates, membrane touch switch assemblies and graphic overlays. Applications requiring good "holding power" under stress and load.
  • New touch sensor uses trapped acoustic resonance technology to monitor contacts
    resonance and monitors its decay. * A thicker substrate in the ActiveTouch switch reduces the possibility of damage due to vandalism. How capacitive sensors work: touch ( Touch-sensitive devices have become common in cell phones, industrial touch panels, and appliances. These devices typically use
  • Capacitive Touch Sense Solutions
    . The Silicon Labs Capacitive Touch Sense solution uses the switch capacitor as part of a simple resistor-capacitor (RC) relaxation oscillator. In addition to being smaller, more reliable, and more cost-effective than physical switches, touch sense switches are also easier to manufacture because they do
  • Mechanical Switches
    of contacts or returns to the original position. Mechanical-bail switches have separate switching assemblies, which are interlocked so that actuation of one switch deactivates another. A capacitive touch switch consists of two conductive layers on opposite sides of an insulating material such as glass
  • One-Touch-Down Circuit for Power Windows and Power Sunroofs: Application Overview
    , or "one touch" operation begins. Current flowing through the motor is monitored, by measuring the voltage drop across a precision value sense resistor. When the motor reaches the end of the travel, "stall condition", the current flowing will typically increase by several times the run current value
  • Switch Contacts
    Mass-produced switch contacts have an rms roughness ranging from 0.5 to 1 10 in. These "smooth " surfaces, in reality, comprise microscopic peaks and valleys. As a result, two mating contacts touch only at the surface peaks or asperities. Contact force between the two surfaces plastically flattens
  • Bonding for Use on Nameplates and Graphic Overlays - HPA 1902/1905(.pdf)
    Designed for use on nameplates, membrane touch switch assemblies and graphic overlays. Applications requiring good "holding power" under stress and load.
  • Guideline for Designing Membrane Switches and Graphic Overlays (.pdf)
    Ideally, the touch panel should be designed simultaneously with the product on which it will be used. The article overviews the guidelines for designing membrane switches and graphic overlays for their optimum results.
