Today, I'd like to introduce the difference between light touch switch and mechanical button. It's easy for us to distinguish them when we use them.

The light touch switch and the mechanical button are also the characteristics of many products. Do you know the difference between them? Our staff will do a simple analysis with you through this article.
1. The cost of lightly touching switch with lamp must be high, and its life is not absolute.
2. The mechanical key is a light touch switch which is usually controlled by a computer board in the semi-automation period.
When the light touch switch is switched off, it is reset, that is, the locking mechanism should work in relation to the power supply. The finished product does not seem to be available, because this requirement can be achieved by using a circuit consisting of a general button switch and a relay. But if only one relay (or contactor) is used, a group of normally open contacts are used to control the power supply of the working coil of the relay (contactor), and the relay weighing iron is regarded as the power supply. When the switch button is pressed, the contacts of the relay control coil are closed, the coil is energized, the relay keeps suction (self-locking), and the other contacts control other lines.
