Core Functionality
These limit switches provide real-time detection of elevator car position within the hoistway. The micro switch contact is activated by the roller mechanism, sending switching signals to the main elevator control system. This enables critical functions including speed change, deceleration control, and limit position protection to prevent overtop and bottoming scenarios, ensuring safe and reliable elevator operation.
Application Scenarios
Ideal for elevator hoistway applications requiring precise position detection for speed change, deceleration, and limit functions. Suitable for both new installations and replacement parts in existing elevator systems.
