FAQs
- Q: How does a tappet-controlled time switch work?
A: The timer uses mechanical tappets (segments) positioned around a rotating dial to open or close contacts at set times, driven by a synchronous clock motor. - Q: What is the difference between 24-hour and weekly versions?
A: 24-hour timers repeat the same schedule daily, while weekly timers allow unique settings for each day of the week, ideal for varying work schedules.
