What Are The Causes Of Micro Switch Poor Exposure?

Reason 1: Garbage and dust are attached.

Countermeasure 1: Eliminate the causes. Or put in a box or use a sealed switch.

Reason 2: The effect of malignant gases in the environment, or the formation of an insulating coating on the contact surface due to the switch in the low load area.

Countermeasure 2: Replace the switch containing the contact material with better environmental adaptability (gold, alloy, etc.).

Reason 3: Immersed solder cosolvent.

Countermeasure 3: To correct the solder method, use a switch that will not be immersed in flux.
