Huizhou Toggle switch A new generation of photoelectric switch devices manufactured using integrated circuit technology and SMT surface equipment processes, featuring intelligent functions such as delay, pulse width expansion, external synchronization, mutual interference resistance, high reliability, stable operating range, and self-diagnosis. This novel photoelectric switch is an automatic photoelectric detection system type electronic switch using pulse modulation. The cold light sources used include infrared light, red light, green light, and blue light, enabling non-contact, non-destructive, rapid sensing and control of various solids, liquids, transparent bodies, black bodies, soft bodies, and smoke conditions and actions. Driving waterproof and explosion-proof switches: Contact-type travel switches have defects such as low response speed, poor accuracy, simple contact detection that easily damages the detected object, and short lifespan. Transistor proximity switches have short effective detection distances and cannot directly detect non-metallic materials. However, the new photoelectric switch overcomes these defects, and also features small size, multiple functions, long lifespan, high accuracy, fast response speed, long detection distance, and strong resistance to light, electrical, and magnetic interference.

 The following introduces Toggle switch the component structure:
　　1. Iron shell (Material: generally iron; Processing: treated by nickel plating or blackening process to prevent oxidation)
　　2. Plastic handle (Material: generally POM; if fire retardant and high temperature resistance are required, PA nylon is commonly used; Processing: injection molding)
　　3. Terminal (Material: generally phosphor bronze; Processing: silver plating)
　　4. Insulating base plate (Material: bakelite; Processing: stamping molding)
　　5. Contact code piece (Material: generally phosphor bronze; Processing: silver plating)
　　6. Round wave bead (Material: generally stainless steel; Processing: nickel plating)
　　7. Spring (Material: bronze; Processing: stamping molding)
　　8. Decorative oil (Material: red or green oil, a type of chemical oil, applied to the contact area between the terminal and the base plate for decorative effect. Generally required to be non-toxic and environmentally friendly).
