Limit Switch SPDT Micro Right Angle 1A 3Pin
🖲️ SPDT Micro Limit Switch – Right Angle, 125V 1A, 3-Pin
The SPDT Micro Limit Switch (Right Angle type) is a compact, precision switch used for mechanical limit detection, position sensing, and end-stop control in a wide variety of applications. Its 3-pin SPDT (Single Pole Double Throw) configuration allows for both normally open (NO) and normally closed (NC) output, making it highly flexible for automation and embedded control systems.
