Quality material for longlasting durability. Waterproof cover protects the dual push buttons used to start and stop your equipment, helping ensure reliable operation in challenging environments. ON push button is selflocking; OFF push button automatically resets. Different colors for the two buttons provide quick recognition, a clean appearance, and convenient operation. Use scenarios: In a workshop or on a job site, use to control power to a pump, compressor, or other essential equipment for safer and easier startup and shutdown. In outdoor setups such as irrigation systems or garden equipment, use to reliably start and stop devices with clearly colorcoded controls. In small mechanical or electrical setups, use to provide a simple, userfriendly control interface that reduces misoperation and improves workflow.
