Micro Limit Switch (5A) with Medium Lever – SE 940

Overview & Features Ensure precise mechanical positioning and reliable contact switching with the SE 940 Micro Limit Switch (Medium Lever) . Operating on a highly responsive snap-action mechanism, this standard SPDT (Single Pole Double Throw) lever switch is an essential electromechanical component for triggering endstops, detecting door closures, and sensing physical limits in automated systems. Available at Tomson Electronics, this compact limit switch is equipped with a medium-length straight metal lever, reducing the physical actuation force required while offering a distinct, tactile click upon contact. It is rated for a continuous 5A load, making it suitable for both logic-level microcontroller inputs and direct switching of low-power AC/DC loads. The robust flame-retardant body and silver-plated brass terminals ensure high durability and a mechanical lifespan exceeding 100,000 operations.
