How to use waterproof Micro Switches correctly


1. Operation method of Waterproof Micro Switches

(1) Do not apply force repeatedly. If the handle button has been pressed and further pressurized, the excessive load weight may cause deformation of the reed (shrapnel), which may cause malfunction.

(2) Especially when an excessive load is applied to the lateral pressure type, the riveted portion may be damaged, which may cause damage to the micro switch. Therefore, during installation and operation, please be careful not to add a load weight higher than the excessive load weight .

(3) Please set the Mini Micro Switch in the direction where the handle can move in the vertical direction. Pressing only one side of the handle, or diagonal operation may result in reduced durability.

2. Countermeasures against dust in the waterproof micro switch

Because it is a Metal Micro Switch without a sealed structure, do not use it in a dusty place. When you have to use it, you should consider using protective measures such as covering.

3. The printed circuit board of the Waterproof Micro Switches should use the single-sided substrate with t=1.6mm as the standard

(1) When using substrates with different thicknesses and substrates with double-sided perforations, it may affect the fit gap of the switch, substrate insertion, heat resistance of solder joints, these will vary according to the perforation and substrate design, so it is recommended to implement Perform a confirmation test.


(2) When mounting theMini Switches on the printed circuit board and performing the board division operation, scattered board powder may enter the switch, so please be careful. Especially in the case where the substrate division powder or foreign matter adheres to the switch due to the surrounding environment or the table, the container and the substrate overlap prevention, it is likely to cause poor contact.
