  • Function:45° Tilt Detecting within a 360° radius
  • Housing made of high insulation material, free from electric conduction and rust problem.
  • Gold-plated ball and terminals, low possibility of oxidization.
  • Simple ON and OFF signals, easy for design.
  • RoHS compliance, an ideal substitute for mercury switch.
  • more economical tilt and rotation detection option than IC design solution.
  • All made in Taiwan and examined before shipment.
  • Do not try to clean the switch with a solvent or similar substance after the soldering process.
  • Suggestion for usage: For vibration usage or application, we suggest to add hysteresis for IC; if vibration is heavy, optical type of sensor switch is recommended.
  • For the continued product improvement as one of the company policy, specifications may change or update without notice. The latest information can be obtained through our sales offices. Normally, all products are supplied under our standard conditions.

As for the Roll Ball Switches, a tiny ball in the switch rolls when motion is detected, triggering a contact of metal terminals. This will generate the conductive or non-conductive status.They provide accurate control for a wide variety of applications like any angle change detecting or vibration detecting and so on.
