Tact switch classification The types of tact switches are standard type, sealed type, SMD type, waterproof type, pendulum type, long type, vertical type, semi-circular array thin type, etc., with light type (red, yellow, green), and the appearance is square, Rectangular type, round type, flat type, convex type, vertical type, long-life type, the main installation forms are plug-in welding type, embedded pin type, surface mount, etc.The advantage of light touch switch is that it is suitable for high-density surfaces Mounting, some can be cleaned after soldering, sealed type can be waterproof and dustproof, very suitable for harsh environments, simple circuit design, product life ranging from 100,000 to 10 million times. Application of light touch switch At present, light-tact switches with light are widely used in portable consumer digital electronic products, household appliances and office supplies, instrumentation and other fields, such as a set of color TV sets of 6 applications, and a set of combined audio applications about 20 sets. Nowadays, the scope of application is still expanding, and the main areas are medical electronic products, car audio, automatic control systems, testing and measuring equipment, automobile transportation and so on. The tact switch market continues to be optimistic, and the competition is becoming more and more fierce. It is mainly manifested in the production specialization and automation. The output has become more and more concentrated in a few powerful and large-scale enterprises, plus DC power supplies. The price of sockets has been falling all the way, and the profit margin is getting smaller and smaller. The situation of one or two hundred companies producing more than a decade ago or more than 20 years ago has been changed. Production is basically concentrated in more than a dozen representative foreign-funded companies and mold technologies. In the hands of joint-stock and private enterprises with strength and advanced processing equipment. Tact switches have now become the most demanded switch category in China, and they are also one of the most exported and imported products.

Working principle of self-locking tact switch The self-locking tact switch is a kind of passive components and cannot be used alone. It can only be used with active components to form a set of control system, and its function can be brought into full play. The working principle of the normally open tact switch: press the switch button to turn on the switch when it is working, and the switch is off when the button is released, and its internal structure is realized by the force of the metal shrapnel. The principle of normally closed tact switch: Press the switch button to turn off the switch while working, and the switch is turned on when you release your hand. How does the self-locking tact switch work？ (1) When the power is turned on, when C9 is charging, the base and emitter of transistor Q1 are connected to the positive electrode of the battery power supply, Q1 is turned off, and the base of transistor Q2 is turned on to ground and Q2 is also cut off, so the circuit is cut off. , VCC 0V. (2) When the touch switch is pressed, C9 discharges and C10 charges. Since the capacitor voltage of C9 does not change immediately, the base voltage of Q2 immediately becomes the capacitor voltage of C9. In other words, Q2 quickly saturates and ignites, while C9 discharges through R18. Set the collector voltage of Q2 to a saturation voltage of 0.3V. At this time, the voltage of the capacitor C9 is also 0.3V, and the voltage of the capacitor C10 is also 0.7V. The battery power is distributed in series through R16 and R17, where Q1 is saturated and turned on, so the circuit is turned on. When turned on, VCC is approximately the battery supply voltage. (3) When the touch switch is pressed again, C9 is 0.3V and C10 is 0.7V, so C9 is charged and C10 is discharged, so the node of Q2 is reverse biased and the battery is on time. It charges C9 to R18 and is based on Q1. The pole voltage increases, Q1 turns off, the circuit turns off, and VCC becomes 0V.
