Sealed Push Button Switch Attention Problem
Jan 26, 2019

Sealed push button switch attention problem

When welding the sealed push button switch terminal, if a load is applied to the terminal, it may be loose due to different conditions, and the deformation and electrical characteristics may deteriorate. Please pay attention when using it.

When using a through-hole printed circuit board or a board other than the recommended one, the influence of thermal stress will change, so check the soldering conditions beforehand.

When performing two weldings, please perform the first welding part after returning to normal temperature. Continuous heating may deform the outer peripheral portion, loosening of the terminal, falling off, and deterioration of electrical characteristics.

Regarding the condition setting of the sealed push button switch, 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 check separately.

For printed circuit board mounting holes and modes, please refer to the recommended dimensions listed in the product drawing.

The switch should be used to directly operate the switch according to the structure of the switch. Please do not use it for mechanical testing.

When the sealed push button switch is operated, if a specified load is applied, the switch may be damaged. Be careful not to apply more than the specified force on the switch.

Please avoid using the operation section from the side.

For the flat shaft type, press the center of the switch as far as possible. For the hinge structure, the shaft will move when pressed, so please pay special attention.

After the sealed push button switch is installed, contact the professional if it passes through the heat storage hardening furnace due to the hardening of the adhesive of other parts.

If corrosive gas is generated in the material around the machine using the switch, it may cause contact failure, so please confirm it beforehand.

The carbon contact point has a characteristic that the contact resistance changes due to the pushing load. For use in voltage divider circuits, etc., please use them after sufficient confirmation.

For models other than the sealed type, please pay attention to the intrusion of foreign matter.
