What is the service life and type of tap switch? The specific details are as follows.
At present, the light touch switch on the domestic market varies according to the application requirements. The mechanical life of the switch varies from 3W times to 10W times, generally 3W, 5W, 8W and 10W times. In China, beryllium bronze, tin bronze and stainless steel are generally used as reed. The light touch switch produced by Dongguan Chenxin Electronic Technology Co., Ltd. can reach more than 10W times at most. Touch switch several definitions in gb14048.2 (compulsory standard, if you want to know more about low-voltage circuit breaker, please refer to this standard) circuit breaker: a kind of mechanical switch that can make, carry and break the current under normal circuit conditions, and also can make and carry a certain time and breaking current under regular abnormal circuit (such as short circuit). Molded case circuit breaker: with A circuit breaker having a housing made of molded insulating material as an integral part of the circuit breaker.
Touch switch is generally based on no auxiliary press accessories, and evolved into small line program and large line program. It can participate in different auxiliary press accessories according to the needs, and can be divided into button type, reed roller type, lever roller type, short boom type, long boom type and other forms according to the different press accessories switches.
Air circuit breaker: it is convenient and safe to open and close the circuit breaker by gently touching the switch under atmospheric pressure. The product can be easily opened or closed for easy use. When it is opened or closed, it cannot significantly hinder the activities or movements of people or objects in the building. Touch the switch gently and it shall be convenient for cleaning the ground. The ground socket shall have different protection levels to get used to the application environment with different requirements, so as to ensure the safe use of users. Reset after power failure, that is to say, the arrangement of work shall be related to the power supply. It seems that there is no product. Because of this requirement, the circuit composed of general button switch and relay can be reached. However, if only one relay (or touch device) is used, a group of normally open contacts are used to control the power supply of the relay (touch device) work coil, and the relay balance iron is used as the switch button. Press After lowering the balance iron, the contact of the relay control coil is closed, the coil is powered on, the relay adheres to closing (self-locking), and other contacts control other lines. The variety of light touch switch is complex, with hundreds of internal structures, including common type, small type and ultra small type according to body integral; waterproof type, dust-proof type and explosion-proof type according to protection function; common type and high temperature resistant type according to application environment.
