Product Overview
This premium SPDT (Single Pole Double Throw) Micro Limit Switch is engineered for high-precision, sub-miniature automation and sensing applications. Featuring a robust teal-green thermoplastic housing, this component is designed with an integrated straight, flat stainless-steel lever actuator that amplifies physical mechanical force to trigger internal contacts with minimal displacement.
Equipped with three heavy-duty male quick-connect terminal lugs, the switch provides an intuitive, reliable interface for common industrial, commercial, and DIY electronic wiring configurations. A clear, laser-etched internal wiring schematic is stamped directly on the side profile for error-free installation.

Operating Mechanics & Wiring Options
The component offers dual-state operation based on how it is wired into your control circuit:
- Normally Closed (NC) Loop (Pins 1 & 2): Current flows naturally through the system while the lever is untouched. Pressing the lever immediately breaks the circuit, cutting off downstream power (ideal for emergency safety stops, door interlocks, or top-of-travel limits).
- Normally Open (NO) Loop (Pins 1 & 3): The circuit remains completely broken and inactive at rest. Depressing the metal lever snaps the contacts shut, completing the path to activate alarms, indicator lights, or start a secondary cycle.

Common Applications
- Industrial Automation & Robotics: End-of-travel limit detection, safety interlocking, and axis homing configurations.
- 3D Printers & CNC Machines: Serves as a physical X, Y, or Z-axis endstop to prevent mechanical over-travel.
- Appliances & Consumer Tech: Door position detection in microwaves, refrigerators, security gates, and arcade cabinet triggers.
- Automotive & Prototyping: Custom button panels, automated valve sensors, and low-voltage relay triggering.
