Matters relating to the use of dip switches？

Dial SWITCH is a Switch in the more common type, in which a lot of decoration is used in the dial switch, the use of the time we also want to pay attention to a lot of key points, the following we will talk about the use of the dial switch in the use of what we have to pay attention to matters?
1. The Dip Switch is not a sealed structure, so it can not be washed.
2. When mounted on a through-hole printed circuit board, the impact of thermal stress on the switch will increase compared to a single-sided board. Please check the specification of heat resistance of solder beforehand                                     

3. Reflow soldering. When reflow soldering with a hot air oven or infrared oven, operate under permissible conditions. In addition, the temperature of the switches and terminals may vary depending on the type and size of the board, and the density of the boards to be soldered, so be sure to prepare in advance.
4. Avoid applying pressure to the terminals when soldering. Otherwise, the electrical and mechanical characteristics may be degraded. Please note
