  • Function: Shock detecting
  • The RBS021002 acts like a normally closed switch which chatters open and closed as it is tilted or vibrated. Note that the RBS021002 is not guaranteed to be closed --- occasionally the sensing mechanism may remain open when at rest. The engineer should design his or her software to look for high-to-low and low-to-high edge transitions rather than an open or closed state of the switch.
  • Tiny size, suitable for small space.
  • Wing-shaped terminals, a feature enables half body of the sensor switch to be buried into PCB.
  • Gold-plated ball and terminals, low possibility of oxidization.
  • All plastic materials subject to industrial purpose, resist high temperature and meet fireproof function.
  • Simple ON and OFF signals, easy for design.
  • RoHS compliance, an ideal substitute for mercury switch.
  • A more economical tilt and rotation detection option than IC design solution.
  • Do not try to clean the switch with a solvent or similar substance after the soldering process.
  • All made in Taiwan and examined before shipment.
  • 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.
