Tact switch is also called the key switch, when it is used tomeet the operating force condition to press switch operationdirection switch closed connected, when revoking pressureswitch is disconnected, its internal structure is on the metal spring force changes to realize on-off.

Tact switch by: insert, base, shrapnel, button, cover plate of the waterproof type touch switch with a layer of polyimide films in the shrapnel.

Tact switch contact resistance load small, precise operationforce error, specification diversification and other advantages,is widely used in electronic equipment and white goods such as: audio and video products, digital products, remote control,communication products, household appliances, security products, toys, computer products, fitness equipment, medical equipment, Yanchao pen, laser pen button etc.. Because touch switch to environmental conditions (pressure less than 2 times the elastic / environment temperature and humidity conditions and electrical properties) of large equipment and button high load using conductive rubber or pot switch metal shrapneldirectly instead of, for example, medical equipment, the TV remote control, etc..

About five feet of touch switch pin: two pin as a group, to the correct pressure switch is communicated four pin, fifth pin toground effect.

Matters needing attention when using the touch switch

1 to touch the switch terminal welding, if applied load in theterminal, due to different conditions, there will be loose,deformation and electric characteristic deterioration may,please pay attention to the use of.

2 the use of circuit board outside the hole of printed circuit board and the recommended, because of the influence of thermal stress will change, so please prior to full confirmation of welding conditions.

3 to two times when welding, please again after the firstwelding part recovered to the normal temperature. Continuousheating may make the peripheral part deformation, terminalloose, reduce the loss and electrical characteristics.

4 on the set welding conditions, need to confirm the actualproduction conditions.

5 product manufacturing as the premise to DC resistance load.The use of other load [inductive load, capacitive load], pleaseorder confirmation.

The 6 printed circuit board mounting hole and mode, pleaserecommend size recorded according to product diagram.

The 7 switch please directly by the people for the operation according to the switch structure. Please do not used for the detection of functional mechanical.

8 touch switch operation, if the applied load specified above,the switch will be the possibility of damage. Please pay attention not to impose requirements more force on the switch.

9 please avoid from the side according to the operationDepartment.

10 for the horizontal shaft type, try to press the switch center.The hinge structure, pressing shaft press position will move,please pay special attention to.

The 11 switch is installed, because other parts of the adhesive is cured by heat hardening furnace, please contact withprofessionals.

12 If the switching of material around the corrosive gas produced, will likely result in bad contact phenomenon, so please prior to full confirmation.

13 points of contact with carbon by pushing pressure loadcharacteristics of contact resistance change. For a voltagedivider circuit, please fully recognized after use.

14 on the closed outside the model, intrusion of foreign bodies,please give full attention
