Current circuit must have switch control, among which touch switch is commonly used by us, so how to control the current circuit? Let's give you a detailed introduction.
How to Control Current Path by Touching Switch
Light touch switch can be divided into low-voltage plastic case key switch and low-voltage frame key switch. The former is used for low-voltage low-current, the latter is used for low-voltage high-current, and the low-voltage plastic case circuit breaker is commonly called automatic key switch.
Several definitions of the Chinese national standard GB14048.2 for lightly touching switches (compulsory standard, depending on this standard if you want to know more about low-voltage circuit breakers):
1. Circuit Breaker: A mechanical switching device that can turn on, load and break the current under normal circuit conditions, and also turn on and bear certain time and breaking current under specified abnormal circuit (e.g. short circuit).
2. Plastic case circuit breaker: a circuit breaker with a shell made of moulded insulating material as an integral part of the circuit breaker.
3. Air Circuit Breakers: Circuit Breakers with Contacts Interrupting and Closing at Atmospheric Pressure
4. Easy to use and safe. The product can be opened or closed conveniently for use, and can not obviously hinder the movement or movement of people or objects in the building when it is opened or closed. And should be able to ease the floor cleaning work. Ground sockets should have different levels of protection to meet different requirements of the use of the environment to ensure the safe use of users.
Dongguan light touch switch reset after power off, that is, the locking mechanism should work in power supply-related, the finished product does not seem to have, because this requirement can be achieved by using the circuit composed of general button switch and relay;
But if only one relay (or contactor) is used to control the power supply of the working coil of the relay (contactor) with a group of normally open contacts, the relay weighing iron is used as a switch button. After pressing the weighing iron, the contacts of the relay control coil are closed, the coil is turned on, the relay keeps the suction (self-locking) and the other contacts control other lines.
