Contact Bounce or Chatter or Bridging, is the undesired intermittent closure of open contacts or opening of closed contacts. It may occur either when the reed contact is operated, released or when subjected to external shock or vibration.
When a reed contact is actuated and the blades touch one another under the force of actuation, they are supposed to establish continuity in a single, crisp moment. Due to the mass of the moving blade and the spring-back, a reed contact will “bounce” upon closure for a small period before coming to a full rest and providing unbroken contact. Bounce time is typically less than 1 mill-second, but can be reduced progressively by using stronger magnets.
