1.
|
Appling load to terminals during soldering under certain conditions may cause deformation and electrical property degradation.
|
|
|
|
2.
|
Avoid use of water-soluble soldering flux, since it may corrode the switches.
|
|
|
|
3.
|
Check and conform to soldering requirements under actual mass production conditions.
|
|
|
|
|
|
5.
|
The products are designed and manufactured for direct current resistance. Contact us for use of other resistances such as inductive（L）or capacitive（C）
|
|
|
|
6.
|
The circuit setting（software setting）shall be ensured for error-free operations, caused by bounce and chattering as specified by each model of the switches.
|
|
|
|
7.
|
Do not use the switches for a long time near the upper or lower limits of the specified operating temperatures. The use environments shall satisfy the specified range of the environmental tests in the specifications.
|
|
|
|
8.
|
In case of continuous operation near the upper and lower limits, see requirements of each model to check if possible.
|
|
|
|
9.
|
The switches designed specifically for automotive uses can be used for vehicles. No other switches shall be used for vehicles.
|
|
|
|
10.
|
Use the switches sufficiently distant（i.e. at a position closer to the full distance）from the ON Start Position.
|
|
|
|
11.
|
The switch-returning force cannot be used as a mechanical driving force of a set.
|
|
|
|
12.
|
Do not apply transverse force to the operating part while piling up PC boards in process and during transportation.
|
|
|
|
13.
|
Protect small and thin switches from external forces in the set mounting process.
|
|
|
|
14.
|
Use of a through-hole PC board, or a PC board of different thickness from the recommendation will have a different heat stress. Verify the soldering requirements thoroughly before use.
|
|
|
|
15.
|
Warped PC boards may change their properties. Carefully design and lay-out the patterns.
|
|
|
|
16.
|
Use of thinner PC boards will require extra care, since the switches may be floated.
|
|
|
|
17.
|
Use of the switches in a dusty environment may lead the dusts entering through the openings and cause imperfect contact or malfunction. Take this into account for set design.
|
|
|
|
18.
|
Corrosive gas if generated by peripheral parts of a set, malfunction such as imperfect contact may occur. Thorough investigation shall be required beforehand.
|
|
|
|
|
|
(1) Store the products as delivered, at a normal temperature and humidity, without direct sunshine and corrosive gas ambient. Use them at an earliest possible timing, not later than six months upon receipt.
|
|
|
|
(2) After breaking the seal, keep the products in a plastic bag to shut out ambient air, store them in the same environment as above, and use them up as soon as possible.
|
|
|
|
(3) Do not stack too many switches.
