Installation Instructions and Notes


  • The connecton type with wire and suitch or indicator light: connector type, terminal type, pin welding type or other types according to thelproduction type.
  • The Connector connection is our patent With quick dismounting, good contact, reliable protection terminal, beautiful appearance, etc, we strongly recommend that you'd better use this type of connection preferentially. Please note following issue when adapting the pin welding connection: 20-30W electric soldering iron will be highly recommended, Control the temperature within 300-330. And you must finish the welding within 2 seconds after adding the soft solder Or your misoperation will lead to the plastic out of shape, switch with bad contact, insensitive action, etc. Please follow these instructions.



  • Switch and Indicator light have the dustproof and waterproof sealing ring inside themselves. The terminal of the surface has up to the IP65, IP66, IP67 performance grade of high dustproof and waterproof. IP65-Dustproof totally, keeping from the water spraying but permitting little water in IP66-Dustproof totally, keeping from the water spraying mightily and permitting little water in.
