Product Overview
The Micro Limit Switch Roller Lever 19mm from Pro Tronix offers a smaller footprint for projects where standard 28mm switches are too large. The 19mm roller lever is specifically designed to handle lateral movement from cams or sliding parts with minimal resistance. Despite its compact size, it maintains a robust 5A/250V rating, allowing it to interface directly with high-voltage AC circuits or low-voltage DC microcontrollers like Arduino and ESP32.

Key Features
Compact Efficiency: The 19mm lever provides a short, precise throw, ideal for tight mechanical assemblies.
Low Friction Design: The integrated roller allows for smooth, repeated contact without wearing down the triggering mechanism.
Quick Response: Pro Tronix ensures a high-speed snap-action mechanism for instantaneous electrical state changes.
Versatile Connectivity: Three-pin design allows for “Normally Open” or “Normally Closed” wiring to match your specific logic needs.
Common Applications
Small-Scale CNC: Used as an ultra-compact end-stop or homing sensor.
Mechanical Counters: Reliable sensing for high-speed object counting on assembly lines.
Smart Furniture: Detecting when small drawers or cabinet doors are fully closed or opened.
Vending Machines: Sensing coin drops or mechanical arm positioning.
