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.
|
|
|
|
4.
|
When soldering twice, wait until the first soldered portion cools to normal temperature. Continuous heating will deform the external portions, loosen or dislodge terminals, or may deteriorate their electrical characteristics.
|
|
|
|
5.
|
Flux from around and above the PC board should not adhere to the switches.
|
|
|
|
6.
|
After mounting the switches, if you intend to put the board into an oven in order to harden adhesive for other parts, please consult with Alps.
|
|
|
|
7.
|
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.
|
|
|
|
8.
|
Protect small and thin switches from external forces in the set mounting process.
|
|
|
|
9.
|
Insert these switches to the specified mounting surface and mount them horizontally. If not mounted horizontally, these switches will malfunction.
|
|
|
|
10.
|
The products are designed and manufactured for direct current resistance. Contact us for use of other resistances such as inductive (L) or capacitive (C).
|
|
|
|
11.
|
The switch will be break if you apply a greater stress than that specified. Take great care not to let the switch be subject to greater stress than specified.
|
|
|
|
12.
|
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.
|
|
|
|
13.
|
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.
