Feature: 1. PP PLASTIC SHELL: The micro switch adopts PP plastic shell, which is waterproof and oil resistant, with high mechanical strength and good impact resistance. 2. GOOD CONDUCTIVITY: Adopting thickened copper conductors and silver contacts, with good conductivity, low resistivity, no arcing, and greater load bearing capacity. 3. SEALING STRUCTURE: The front rear covers and cylinder body adopt a riveted roll wrap structure, ensuring strong sealing performance, stable and reliable connection. 4. MECHANICAL ACTION: The micro switch has smoother mechanical action and a wide range of actuators, including styles with adjustable action positions. 5. WIDE APPLICATION: Widely used in conveyor belts, elevators, parking lots, mechanical processing, packaging machinery, semiconductor manufacturing, etc. Specification: .Item Type: Micro Switch Rated Voltage: 250VAC Model BM 7144 Operating Force Maximum: 280g / 0.6lb Restoring Force Minimum: 100g / 0.22lb Pre Travel Position Maximum: 6.5mm Over Travel Minimum: 2.0mm Movement Differential Maximum: 1.5mm Action Position: 50±1.2 Free Position: Approx. 56mm / 2.2in Operating Speed: 0.01mm to 50cm per sec (locking plug type) Action Frequency: Mechanical: 120 Times Per Minute, Electrical: 30 times per minute Contact Resistance: Below 15mΩ (initial stage) Insulation Resistance: Above 100mΩ (below 500VDC) Dielectric Strength: Between Discontinuous Terminal: 1000VAC, 50/60Hz, lasting for 1 minute Between Current Carrying and Non Current Carrying Part: 1500VAC, 50/60Hz, lasting for 1 minute Terminal to Ground: 1500VAC, 50/60Hz, lasting for 1 minute Vibration Malfunction Durability: 10 to 55Hz, 1.5mm dual amplitude Impact Mechanical Durability: 1000m/Sec² (About 100G/S) Impact Malfunction Durability: 300m/Sec² (About 30G/S) Ambient Temperature: -10-80℃ (without freezing) Humidity: <95% RH Mechanical Life: Over 10000000 cycles (at rated OT value) Electrical Life: Over 500000 times Non Inductive Load Resistive Load NC 10 NO Bulb Load NC 2.5 NO 1.25 Inductive Load Inductive Load NC 10 NO Motor Load NC 3 NO 1.5 Package List: 2 x Micro Switches
