Application
Renew’s miniature limit switches play a critical role in ensuring the safety, precision, and reliability of various devices across different fields. Here are some popular or potential application.
These limit switches are commonly used in escalators and electric walkways, where they play a very important role in ensuring safety and operating efficiency. They play a great role in monitoring and controlling various components. For example, a roller plunger limit switch can detect if an escalator step is misaligned or if a handrail is damaged. If a problem is detected, the switch triggers an emergency shutdown to prevent an accident.
