What are chattering problems for a basic switch?
When switching contacts, chattering (the moment the contacts leave) and bouncing (the moment the contacts come in contact) always occurs in a basic switch with contacts. Chattering and bouncing may vary depending on the switch operating speed, switch operating load, and contact corrosion, while contact resistance may become unstable at the switching point.
Chattering occurs right before the contacts are switched (NC to NO, NO to NC). Specifically, the slower the actuator is operated, the longer the amount of time contact resistance is unstable. This unstable contact leads to unstable output signal and may result in equipment stoppage.
Extremely Slow Operating Speeds:
The contact between the contacts becomes unstable and chattering occurs.
Incorrect signals are output and arcing causes contact deterioration.
