The KW10-DZ4P075 SPDT Roller Lever Micro Switch is a sub-miniature, highly responsive contact mechanism engineered to execute crisp circuit changes based on subtle mechanical movements. Built with an internal snap-action spring configuration, the contacts instantly throw positions once the actuation point is crossed, eliminating arcing and contact degradation. The "DZ4" variant is specifically equipped with a steel lever arm tipped with a free-spinning roller wheel, which absorbs structural lateral friction from passing cams or moving plates to prolong the mechanical lifecycle of your system.

Configured as a Single Pole Double Throw (SPDT) component, the switch provides three terminal integration options out of the box: a Common pin (COM), a Normally Open pin (NO), and a Normally Closed pin (NC). This gives designers the flexibility to map the trigger as a circuit interrupt path or a logic high flag inside microprocessor systems. Its exceptionally light 0.75N operating force ensures that low-torque mechanical fixtures can actuate the switch cleanly without binding or stalling.

Key Features & Benefits:

• Friction-Reducing Roller Actuator: Translates linear slide motion from mechanical assemblies into vertical actuation force seamlessly, reducing stress on moving physical joints.

• Highly Tactile Snap Action: Provides instantaneous contact transitioning with an audible, satisfying "click" for immediate confirmation of endstop triggers.

• Sub-Miniature Footprint: The compact, lightweight frame drops effortlessly into tight physical footprints, such as custom 3D printer printhead carriages or micro-robotic chassis.

• Pre-Drilled Structural Mounting Holes: Features two integrated mounting eyelets molded directly into the nylon plastic base block, facilitating firm anchoring via standard M2 mounting screws.

Technical Specifications

How to Wire and Use:

1. Identify Terminals: Locate the COM, NO, and NC pins on the micro switch body.

2. Normally Closed Circuit (Default ON): Connect your power source to COM and your output device to NC. The circuit will remain active until an object depresses the roller lever.

3. Normally Open Circuit (Default OFF): Connect your power source to COM and your output device to NO. The circuit will complete and activate your device only when the roller lever is pressed.

4. Mechanical Mounting: Use the pre-drilled mounting holes to securely fix the switch in place. Ensure the moving mechanism gently glides over the roller lever to prevent mechanical damage.

Common Applications

Thanks to its highly sensitive 0.75N operating force and roller lever design, this micro switch reduces friction and wear, making it perfect for:

• 3D Printers & CNC Machines: Widely used as end-stop or limit switches for the X, Y, and Z axes.

• Robotics: Excellent for obstacle detection bumpers and position sensing.

• Home Appliances: Integrated into microwave doors, washing machines, and smart vending systems.

• Safety Devices: Used as tamper switches, interlocks, and emergency stop mechanisms.

• Industrial Automation: Conveyor belt object counting and mechanical arm position indexing.
