When using through-hole printed circuit boards and PCBs other than those recommended, due to changes in thermal stress, please confirm the welding conditions in advance.
When welding twice, please do it after the first welding part is restored to normal temperature. Continuous heating may deform the periphery, loosen the terminals, drop off and reduce the electrical characteristics.
As for the setting of welding conditions, it is necessary to confirm the actual batch production conditions.
The product is designed and manufactured on the premise of DC resistance load. When using other loads [inductive load, capacitive load], please confirm separately.
For PCB mounting holes and modes, please refer to the recommended dimensions recorded in the product drawings.
The switch should be used for the structure of pressing the switch directly by human operation. Please do not use for mechanical testing function.
When the switch is lightly touched, if the specified load is applied, the switch will be damaged. Please be careful not to exert the above force on the switch.
Avoid side-by-side operation.
For the flat rod type, press the switch center as far as possible. For hinged structures, when pressed, the position of the axle rod will move. Please pay special attention to it.
After the switch is installed, please contact professionals when it passes through regenerative hardening furnace due to hardening of binder for other parts.
If the material around the switch produces corrosive gas, it may cause poor contact and other phenomena, so please make full confirmation in advance.
The carbon contact point has the characteristic of changing contact resistance due to push load. When used in voltage divider circuit, etc., please use it after full confirmation.
For models other than airtight type, please pay full attention to the invasion of foreign bodies.
