The condition mentioned above is the temperature on the Cu foil of the PCB surface.
There are cases where board's temperature greatly differs from switch's surface
temperature depending on board's material, size, thickness, etc. Care, therefore,
should be used not to allow switch's surface temperature to exceed 260ɗ.

Continuous Soldering Time
Max,5 seconds
Precautions in Handling
1. Care should be exercised so that flux from the upper part of the printed circuit board
does not adhere to the switch.
2. Don’t clean the switch body except with top tape sealed type, which can only spray of
cleaning method from top of s/w.
3. Slide the DX48 actuator from
sec operation.
