Force Sensing vs. Simple Switch

Force sensing resistor interface solution  use pressure sensitivity to activate and enable user controls. Variably sensitive and more versatile than a simple switch, FSRs can provide analog control of continuous device functions, such as in the Microsoft X-Box game controller. Use the comparison below to learn more about how FSR control solutions can differentiate your products.

 

FSR

Conventional Switch

Scrolling
  • Analog output enabling scrolling, zooming, or control management, such as volume control
  • Force sensing allows for user controlled scrolling speed
  • Complex menus require enhanced capabilities of analog output sensor
  • No variable input, only on or off
  • Standard offering, same look as competitors

  • Navigating complex menus cause user frustration

 

Product Differentiation

 

  • Sensor can be configured to meet design objective of mobile phone

 

 

  • Very little difference between switch sensors

 

Enhancements

  • Available options include PCB assembly, narrow tail pitch, EL and LED lighting, metallic actuators, PC over silicone actuators
  • Very few, if any, product options

Mechanical
  • Thickness as low as 0.012 inch (0.30 mm)
  • More durable input solution, and a thinner and more streamlined industrial design and device form factor

  • Mechanical switches wear out
