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 SwitchRated Voltage: 250VACModel BM 7144Operating Force Maximum: 280g / 0.6lbRestoring Force Minimum: 100g / 0.22lbPre Travel Position Maximum: 6.5mmOver Travel Minimum: 2.0mmMovement Differential Maximum: 1.5mmAction Position: 501.2Free Position: Approx. 56mm / 2.2inOperating Speed: 0.01mm to 50cm per sec (locking plug type)Action Frequency: Mechanical: 120 Times Per Minute, Electrical: 30 times per minuteContact Resistance: Below 15m (initial stage)Insulation Resistance: Above 100m (below 500VDC)Dielectric Strength: Between Discontinuous Terminal: 1000VAC, 50/60Hz, lasting for 1 minuteBetween Current Carrying and Non Current Carrying Part: 1500VAC, 50/60Hz, lasting for 1 minuteTerminal to Ground: 1500VAC, 50/60Hz, lasting for 1 minuteVibration Malfunction Durability: 10 to 55Hz, 1.5mm dual amplitudeImpact Mechanical Durability: 1000m/Sec (About 100G/S)Impact Malfunction Durability: 300m/Sec (About 30G/S)Ambient Temperature: -10-80 (without freezing)Humidity: <95% RHMechanical Life: Over 10000000 cycles (at rated OT value)Electrical Life: Over 500000 timesNon Inductive LoadResistive LoadNC10NOBulb LoadNC2.5NO1.25Inductive LoadInductive LoadNC10NOMotor LoadNC3NO1.5Package List:2 x Micro Switches
