Micro Limit Switch — compact, reliable limit switch for precise control Key benefits Precise, repeatable control: momentary action and hinge roller lever allow accurate detection of moving parts and consistent contact operation. Easy integration: standard 3-pin terminal and compact size fit tight assemblies and common automation setups. Durable, low-resistance contacts: copper construction provides reliable electrical performance for small-current control circuits. Safety and automation support: designed to open or close control circuits on contact with moving parts, helping prevent overtravel and automate sequences. What it does Type: Micro limit switch, single pole double throw (SPDT) configuration with 1 N/O contact. Action: Momentary operation — contacts change state only while the actuator is engaged. Actuator: Hinge roller lever for smooth mechanical engagement and reduced wear. Key specifications Terminal: 3-pin Contact material: Copper Rated voltage: AC 125 V – 250 V Rated current: 5 A Overall size (pole not included): 20 x 6 x 10 mm (0.8 x 0.2 x 0.4 inches) — compact footprint for confined installations Function: Acts by collision of moving machine parts to move contacts, closing or interrupting the control circuit as required Why customers choose this switch Compact footprint for tight spaces while still supporting standard AC voltage and 5 A current. Roller lever reduces direct impact on the contact mechanism, improving longevity in repetitive operations. Simple 3-pin wiring for straightforward installation and replacement in many equipment types. Designed specifically to trigger from mechanical movement, making it suitable for end-of-travel detection, limit control, and safety interlocks. Typical applications and scenarios CNC or bench machine end-stop: Mount on a carriage or slide so the roller lever detects travel limits and stops motion to prevent overrun. Hoist or elevator limit detection: Use as an upper or lower travel cut-off to interrupt the control circuit when the platform reaches preset positions. Electric motor or automated assembly equipment: Install on moving fixtures to trigger sequencing events, part detection, or safety shutoff during production. Installation and use notes Ensure wiring matches the 3-pin terminal layout for proper SPDT operation and the intended normally open contact. Mount so the roller lever contacts the moving part with smooth motion; avoid sharp impacts that could accelerate wear. Confirm the rated voltage and current suit the control circuit; this switch is intended for small-current electrical control applications.
