The difference and introduction of touch switch and key switch

 

In our daily use, whether it is a touch switch or a key switch, it will be called a key switch. So what is the difference between a touch switch and a key switch? Let's give you a detailed introduction.

What's the difference between a touch switch and a key switch?

An electronic switch can be switched on by pressing the switch button lightly. When the switch is released, the switch is disconnected. The internal structure of the electronic switch is realized by the force and elasticity of metal shrapnel. Micro-switch is widely used in household appliances because of its small size and light weight, such as color TV buttons, DVD machine buttons, computer mouse and so on. However, the micro-switch has its shortcomings. Frequent pressing will make the metal fragments lose elasticity and become ineffective due to fatigue. You can learn more, so now most of the buttons in electrical appliances are replaced by conductive rubber, such as computer keyboard, remote control, etc.

Touch switch is also called button switch, which is different in industry. Travel to distinguish, more than a certain distance is called the key switch, travel is relatively small called touch switch, popular understanding should be. Gently touch the switch on.

What is a key switch?

The key self-locking switch is a device that locks the switch state of its circuit through the mechanical device of the switch itself. When you press the first button, the button is pressed and the circuit is turned on. When you press the button again, it bounces up and the circuit is disconnected.

The word "unlocked switch" is seldom heard. It should refer to the switching switch, which is the kind of circuit that is turned on by pressing down the circuit and disconnected as soon as the hand loosens the circuit.

Of course, the point switch can also form a self-locking switch through the self-locking circuit.

Two point switch and self-locking circuit can form self-locking switch, but this form is more complex than mechanical self-locking switch, and requires professional knowledge. So it only applies to specific occasions.

This is the difference between touch switch and key switch. I hope you can clearly distinguish these problems and their causes.
