Tripod toggle switch is a kind of switch which can be switched by easy toggle. It can avoid touching circuit and causing breakdown when used. So it is used in many circuits. Of course, in the process of purchasing, there will be different types of use, and the quality of materials will appear. Different, so today I would like to introduce a method of selecting toggle switch.
The sliding switch can change the state of the switch contacts without much contact, so the contact capacities are very small, and the structure is simple. The switching force can only be kept in the original state after withdrawal, that is to say, quite a small force can be pressed.
Firstly, the lead base material is pin base material, and the lead base material of tripod switch is brass or phosphorus copper (low grade is iron). In order to reduce the contact resistance, the pin is basically silver plated. The SO2 gas in the air will be oxidized when silver meets the air, which directly affects the solderability and contact resistance of the switch. Therefore, the high quality switch should be turned on first. The silver plating thickness and silver plating process of the pins are controlled.
Second, the final quality of the product after the accessory is the assembly process. The assembly process depends on the management ability of the production company, the staff's quality intention and the quality assurance ability and other factors. The quality of the final product produced by different assurance ability must be different. Now the market assembly method has man-made and machine, because the current automation. In the process of upgrading the chemical capability, each has its own advantages and disadvantages: low cost of machine assembly but low product quality, high cost of manual assembly but high quality.
Third, the key influencing factor of conduction reliability is the structure of the contact point, because the function of the switch is to conduct contact between the contact point and the shrapnel, then the larger the contact surface, the better the contact surface, the contact surface is determined by the structure.
Fourthly, the life and feel of the switch are determined by the combination of the stroke and the shrapnel. The shorter the stroke, the lighter the sound, the longer the life and the longer the stroke. On the contrary, under the condition of fixed shrapnel technology, the life of the switch is mainly determined by the stroke or the sound switching switch. In addition, the key factor determining the life of the shrapnel is the stamping technology.
A new generation of optoelectronic switchgear made by integrated circuit technology and SMT technology has the intelligent functions of delay, broadening, external synchronization, anti-interference, high reliability, stable working area and self-diagnosis. This novel optoelectronic switch is an active optoelectronic probe with pulse modulation. Measuring system type electronic switch, using cold light sources such as infrared light, red light, green light and blue light, non-contact, non-destructive and rapid control of a variety of solid, liquid, transparent body, black body, soft body and smoke and other substances in the state and action, driving water-proof and explosion-proof switch contact stroke switch there is a response speed Low degree, poor precision, contact detection easy to damage the object to be detected and short life shortcomings, and the transistor proximity switch operating distance is short, can not be directly detected.
Measuring non-metallic materials, but the new photoelectric switch overcomes the above shortcomings. The switch is small in size, multi-function, long in life, high in precision, fast in response, long in detection distance and anti-light, strong in electrical and magnetic interference. The variety and mechanical performance specifications of the switch are introduced by the switch. The handle makes the circuit turn on or off, so as to achieve the purpose of switching the circuit. The commonly used varieties of switching switches are unipolar two-position, unipolar three-position, bipolar two-position and bipolar three-position, etc. It is generally used in low-voltage circuits, with the characteristics of flexible slider action, stable and reliable performance.
The switching switch is to switch the circuit on or off by switching the switch handle so as to achieve the purpose of switching the circuit.
The commonly used varieties of dial switch are unipolar two-position, unipolar three-position, bipolar two-position and bipolar three-position, etc. It is generally used in low-voltage circuits, with slider action flexible, stable and reliable performance characteristics, dial switch is mainly used in: various instruments / instrumentation equipment, a variety of electric toys, fax machines, audio equipment, medical treatment. Preparation, beauty equipment, and other electronic products.
