Structure and performances:

COB series button adopts full-plastic case. The appearance is beautiful and the structure is reasonable. The product, which is equipped with rubber cable sheath and waterproof ealing strips, is provided with good dustproof and rainproof performance.

All the other buttons are with function of automatic reset and mechanical interlock structure realizing optimistic and reverse controlling except "on" button of general circuit switch is of function of automatic lock. It not only predigests the circuits, but also efficiently protects the circuits and operation of equipment. Besides, in order to avoid circuits failure more reliably, the "off" button can switch of the general power supply.

Installation and usage

1) Dismantle the end cover and install the sealing sheath. Then fasten them on the end face of the button with screw.

2) Dismantle the bottom cover. After putting all the control lines into the sealing sheath, fasten them at the connection ends of different buttons one by one according to the electrical principle diagram.

3) Examine or check whether the connection is correct. If everything is normal, fix the leading wires after bundling them up. Finally, reinstall the bottom cover.

Color: Yellow, Orange, Red, Green color can be customized
