Comparing with plastic products, metal products not only make improvement in IK degree, but also make progress in IP degree. Most products have reached Ip65, and some have achieved IP67(Soaking for short time) and even more high level. And many clients call the products “water-proof push button”.

Any incorrect welding operations all possibly cause damage to plastic deformation, bad-contact switch ect. When soldering the pin-terminals of switches and signal lamps, we should pay attention to the following points. Because it’s easy to have the switch damaged if improper-operation.

1. Using suitable electric soldering iron and quickening welding speed. We suggest you use 30W electric soldering iron and finish within 2 seconds when it reaches 320℃.
2. Using right amount of scaling powder and putting the pinterminals downwards when soldering.
3. It’s better to use connectors than direct welding
