Key benefits Prevents accidental automatic restarts after a power outage: the switch stays off after power is cut and requires a deliberate press of the green start button to restart equipment. Protects equipment from lowvoltage conditions: undervoltage protection helps reduce motor stress and potential damage during abnormal supply conditions. Clear, safe control and durable protection: distinct green (start) and red (stop) buttons under a PVC waterproof cover make operation obvious and protect the controls from moisture and debris. Simple installation and operation: straightforward mechanical design for easy mounting and use on compatible machines. Main functions and attributes Powerfailure and undervoltage protection: automatically remains off after a power interruption to prevent unintended restarts; includes undervoltage cutoff behavior to protect motors. Twobutton control: green button to switch the unit on; red button to switch it off. PVC waterproof cover: buttons are protected by a PVC cover for improved resistance to splash and contamination. Colorcoded controls: red and green buttons for immediate visual identification. Compatibility: designed for electrical appliances driven by AC 220 V motors. Construction and performance: simple, robust structure intended for reliable, repeated use and straightforward installation. Typical applications (practical scenarios) Food processing shops: control slicers and meat planers so machines do not restart automatically after a power loss, improving operator safety. Workshops and fabrication sites: use with magnetic drills and other AC 220 V motor tools to prevent unexpected startup and reduce electrical stress on motors. Small industrial or commercial equipment driven by AC 220 V motors where safe restart control and basic waterproofing of the control interface are required. Why choose this switch Provides a reliable safety layer against automatic restarts and lowvoltage events while keeping operation intuitive with clearly marked start/stop buttons and a protective PVC cover. Fits directly into setups that use AC 220 V motordriven appliances such as slicers, meat planers, and magnetic drills, offering a practical, easytoinstall control solution without complex wiring or adjustments.
