1.
|
Appling load to terminals during soldering under certain conditions may cause deformation and electrical property degradation.
|
|
|
|
2.
|
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.
|
|
|
|
3.
|
Check and conform to soldering requirements under actual mass production conditions.
|
|
|
|
4.
|
Verify samples with 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.
|
For the sizes of holes and patterns on a PC board for mounting a switch, refer to the recommended dimensions in the product drawings.
|
|
|
|
7.
|
This switch is designed for manually operated units. Must not use this switch for a mechanical detection unit. For detection purposes, please use our detection switch.
|
|
|
|
8.
|
The switch will be broken if impact force or a greater stress than that specified is applied. Take great care not to let the switch be subject to greater stress than specified.
|
|
|
|
9.
|
Do not apply a force from the side of the stem.
|
|
|
|
10.
|
Be sure to push the center switch for "without-stem" type. Extreme care is required for a hinge structure type because the stem press position moves when it is pressed.
|
|
|
|
11.
|
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.
|
|
|
|
12.
|
Corrosive gas if generated by peripheral parts of a set, malfunction such as imperfect contact may occur, Thorough investigation shall be required beforehand.
|
|
|
|
13.
|
Contact resistance of a carbon contact type may vary depending on push force.. Confirm that it functions sufficiently when you use this TACT switch with a voltage divider circuit.
|
|
|
|
14.
|
Be aware of dust intrusion into a non dust-proof TACT switch.
|
|
|
|
|
|
(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.
|
|
|
|
(4) Store the key switches with the switch in the released position.
