Lockable, contactless trigger switch with built-in speed control. Designed for reliable power control in electric power tools such as cutting machines, electric planers and marble machines. Key benefits Lockable trigger: hold the switch on for continuous operation without keeping your finger pressed, improving user comfort and control on long runs. Contactless design: minimizes mechanical wear and delivers more consistent switching performance over time. Built-in speed control knob: adjust motor speed directly from the trigger for precise control of cutting and finishing tasks. Plastic housing: lightweight, insulated casing suitable for tool environments while keeping the switch compact and easy to integrate. Wide compatibility: commonly used in electric power tools to control power and speed, reducing the need for external controllers. Main features Type: lock type, contactless trigger push-button switch Control: integrated speed control (knob) Housing material: plastic casing Typical use: power and speed control in electric tools Practical use scenarios Cutting machine: enable smooth start/stop and variable cutting speeds for different materials while keeping the trigger locked during long cuts. Electric planer: adjust motor speed on the fly to match wood hardness and achieve finer surface finishes. Marble/stone machine: control power and speed precisely when cutting or polishing stone to reduce chipping and improve accuracy. Compatibility and installation notes Intended for use in electric power tools for power and speed control. Check device wiring and mounting requirements before installation to ensure proper compatibility and safe operation.
