1.
|
When terminals are exposed to mechanical stress during soldering, it may cause degradation in deformation and electrical property.
|
|
|
|
2.
|
Through-hole PC board, or a PC board thickness other than the recommendation may cause larger heat stress. Prior verification is highly recommended.
|
|
|
|
3.
|
In prior to the 2nd soldering swith shall be stable with normal temperature. It may cause deformation of swith, loose terminals, terminal removed from PC board, and / or degradation of electric property.
|
|
|
|
4.
|
Verify samples with actual mass production conditions.
|
|
|
|
5.
|
The products are designed and manufactured for direct current resistance. Individual consultation is recommended for use of other resistances such as inductive（L）or capacitive（C）.
|
|
|
|
6.
|
The sizes of holes and patterns on a PC board for mounting a switch, be asper 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 of switch for "without-stem" type. Extreme care is required for a hinge structure type, as the activation point may shift when it is pressed down.
|
|
|
|
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.
|
Prior verification is needed to ensure that no corrosive gas-generating components are used near our switch. It may give negative influence such as contact failure.
|
|
|
|
13.
|
Contact resistance of a carbon contact type may vary depending on push force. Confirm that it functions sufficiently in using 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 prevent out ambient air, store them in the same environment as above, and use all as soon as possible.
|
|
|
|
(3) Do not stack too many switches.
|
|
|
|
(4) Store the key switches in released position.
