Optimize your high-sensitivity sensing with our Miniature Micro Switch with Spring Pin. Unlike standard rigid levers, this switch utilizes a flexible, needle-thin spring wire actuator. This design allows for multidirectional triggering and requires minimal physical force, making it the perfect choice for detecting lightweight objects, thread breaks, or delicate mechanical movements.
High-Flex Spring Pin Actuator: The elongated wire pin provides maximum mechanical leverage, allowing the switch to be triggered by the slightest touch from almost any angle.
Ultra-Low Actuation Force: Designed specifically for applications where a standard metal lever is too rigid to be moved by the target object.
Precision SPDT Configuration: Features a 3-pin layout—Common (COM), Normally Open (NO), and Normally Closed (NC)—for versatile logic integration.
Slim-Profile Housing: The compact black and yellow synthetic body is designed for tight spaces within complex machinery or electronics.
Vertical PCB/Solder Terminals: Features straight, high-conductivity pins for direct mounting onto printed circuit boards or for secure wire soldering.
Reliable Snap-Action: The internal mechanism provides a crisp tactile response and instantaneous electrical switching, even with slow-moving actuators.
This Spring Pin Micro Switch is a specialized solution for:
Textile & Sewing Machinery: Detecting thread presence or breaks in high-speed embroidery and weaving systems.
Paper Handling & Printing: Sensing the passage of thin paper sheets or envelopes in feeders and sorters.
Vending & Dispensing: Detecting lightweight items like plastic cups or snack bags as they fall.
Precision Robotics: Serving as a "whisker" sensor for light-touch obstacle detection.
Actuator Type: Flexible Spring Pin (Wire).
Circuitry: SPDT (Single Pole Double Throw).
Housing Material: High-Impact Synthetic
Mounting: Dual Hole Integrated Chassis Mount.
Can the spring pin be bent to a specific shape?
Yes, the spring wire is flexible and can be carefully shaped or trimmed to suit your specific clearance and reach requirements without losing its spring tension.
What is the advantage of a spring pin over a roller lever?
A roller lever is great for sliding force, but the spring pin is superior for "feathertouch" applications where the object being detected is extremely light and might be damaged or stopped by a heavier rigid lever.
How durable is the wire?
The actuator is made of high-tensile spring steel, designed to flex and return to its original position thousands of times without becoming permanently deformed.
