Description
Product Description The KW11-2 Miniature Micro Limit Switch is a highly sensitive, snap-action contact switch designed for precise mechanical detection and circuit automation in tight spaces. Operating on a Normally Open (NO) or Normally Closed (NC) configuration depending on your wiring layout, this sub-miniature switch instantly changes its electrical state with minimal physical force. Built with an integrated, lightweight straight metal hinge lever, it smoothly translates small mechanical movements into a crisp, tactile click. Its high-grade, flame-retardant plastic housing houses premium silver alloy contacts that ensure reliable, spark-free performance and exceptional electrical endurance over hundreds of thousands of cycles. Key Specifications Model: KW11-2 (often part of the universal KW11 series) Configuration: Available in 2-Pin or 3-Pin SPDT (Single Pole Double Throw) variants. Operation Type: Momentary / Snap-Action (Resets immediately when physical pressure on the lever is removed). Electrical Rating: AC 5A / 125V–250V (Also fully compatible with low-voltage 12V/24V DC signal logic circuits). Actuator Style: Short/Medium Straight Hinge Lever. Compatibility & Applications As a highly standardized component, the KW11-2 is completely universal and non-proprietary. It functions as an exact drop-in replacement for any mini micro switch sharing the same physical dimensions and layout, regardless of the brand. It is widely utilized as a safety interlock, position sensor, or boundary limit trigger in the following setups: 1. 3D Printers & CNC Machinery Axis Endstops: Widely used on Creality (Ender series), Anycubic, and DIY 3D printers to detect when the print head or bed has reached its physical limits (X, Y, or Z-axis homing). Laser Engravers & Cutters: Functions as a home position locator and boundary guard sensor. 2. Consumer Electronics & Small Appliances Microwave Ovens & Toaster Ovens: Acts as an internal door-alignment safety switch to ensure the device only operates when securely closed. Coffee Makers & Juicers: Detects when a water reservoir or pulp container is properly locked into place. Paper Shredders: Senses paper feeding into the slot or verifies if the wastebin is fully pushed in. 3. Robotics & DIY Prototyping Arduino & Raspberry Pi Projects: Ideal for obstacle detection or bump sensors on DIY robotic rovers and automated mechanical arms. Arcade & Gaming Gear: Can be used under custom arcade control sticks or inside token/coin-drop validation mechanisms.
