Performance characteristics
The toggle switch is a new generation of photoelectric switching device manufactured by integrated circuit technology and SMT external device technology. It has intelligent functions such as delay, broadening, external synchronization, anti-interference, high reliability, stable working area and self diagnosis. This novel photoelectric switch is an active photoelectric detection system electronic switch with pulse modulation. The cold light sources used include infrared light, red light, green light and blue light. It can quickly and control the state and action of various substances such as solid, liquid, transparent body, blackbody, soft software and smoke without contact and damage. The contact travel switch driving the waterproof and explosion-proof switch has the disadvantages of low response speed, poor accuracy, easy damage to the detected object and short service life. However, the action distance of the transistor proximity switch is short, so it can not directly detect non-metallic materials. However, the new photoelectric switch overcomes the above shortcomings, and has the advantages of small volume, multiple functions, long service life, high precision, fast response speed, long detection distance and strong resistance to optical, electrical and magnetic interference.
Introduction to the varieties and mechanical performance specifications of toggle switch toggle switch is to turn on or off the circuit by toggle switch handle, so as to achieve the purpose of switching the circuit. The commonly used varieties of toggle switch include unipolar double position, unipolar three position, bipolar double position and bipolar three position. It is generally used in low-voltage circuit and has the characteristics of flexible sliding block action and stable and reliable performance.
matters needing attention
1. Be careful with chemicals. Since synthetic resins such as polycarbonate are used in the bottom plate of the toggle switch, the potentiometer shall not be exposed to the strong atmosphere of chemicals such as ammonia, amine, alkali solution, Sudan, ketone, ester and halohydrocarbon.
2. Avoid using water-soluble flux when soldering with flux, otherwise it will have adverse effects on the metal and other materials constituting the toggle switch.
3. The solder wiring design and soldering method shall avoid causing the molten tin to flow to the upper plane of the PC board, which will cause poor contact.
4. Low temperature work when the product is used in low temperature environment, such as car radio or car audio in cold zone, the company provides hand comfortable products according to customer requirements. Please explain when ordering.
5. The shorter the length of the sliding handle, the better (at least 5mm). When the width a of the sliding handle remains unchanged, the shorter the length of the sliding handle, the better the hand feel, and the higher the output point, the worse the hand feel.
6. The driving arm shall not keep the operating point away from the center line of the sliding handle. For the same reason, the shorter the distance b, the better.
