Release Time:2019-04-22

 
The use of light touch switch is very frequent. It plays an important role in controlling power supply on set-top box and other devices. Therefore, we must pay attention to these problems when we use it and understand the internal on-off method of light touch switch. The following is the details.
Touch switch is an electronic switch, which can be switched on by pressing the switch button lightly. When the switch is released, the switch will be disconnected. The internal structure of the switch is realized by the force and elasticity of metal shrapnel.
The light touch switch is widely used in household appliances because of its small contact resistance, clear touch and complete height specifications, such as video and audio products, digital products, remote controllers, communication products, household appliances, security products, toys, computer products, fitness equipment, medical equipment, banknote checker pen, laser pen keys and so on.
But touch switch has its shortcomings. Frequent pressing will make the metal shrapnel lose elasticity and become ineffective due to fatigue. So now most of the electric buttons are directly replaced by conductive rubber or pot switch hardware shrapnel, such as computer keyboard, TV remote control and so on.
Above is the problem of lightly touching the switch on and off. These problems should be understood clearly and can not disturb us.
