1. Dc switch should adopt insulation transformer and ensure stable voltage mains corrugation.


2. If any electric power live or dynamic line passes through the surrounding of switch lead-wire, in order to precent the switch form damage or error action, cover the metal bushing on the switch lead-wire and ground it to the earth.


3. Set the switch use distance within the rated distance to avoid the effects from temperature and voltage.


4. Wiring while power-on is strictly prohibited, connecting the wires strictly according to the wiring diagram and output return elmentary diagram.


5. If there areany special requirements to the switch like water proof, oil proof, acid proof, base proof, high temperature proof of with any other specifications, the users are required togive clear indication when placing an order, we can produce according to the requirements of the user.
