What is a toggle switch
The toggle switch is used to turn the circuit on or off by flipping the switch handle to achieve the purpose of switching the circuit. The commonly used types of toggle switches are unipolar two-position, unipolar three-position, bipolar two-position and bipolar three-position, etc. It is generally used in low-voltage circuits and has the characteristics of flexible slider action, stable and reliable performance. Mainly widely used in: various instruments/meters equipment, various electric toys, fax machines, audio equipment, medical equipment, beauty equipment, and other fields of electronic products.
Types of toggle switches
1. High current sealed toggle switch
Its rated current is as high as 5A, and it is sealed with epoxy resin, so it is a high-current sealed toggle switch. It has a variety of terminal forms, the contact materials are silver-plated and gold, and the switch functions are diverse. Therefore, there are many types of subdivisions. Widely used in electrical appliances and machinery.
2. Single-sided snap-back surface mount toggle switch
The operation of the actuator is on the side, and the pins are patch type, so it is a single-sided spring-back surface mount toggle switch. Widely used in communications, digital audio and video.
3.4P3T in-line toggle switch
The contact form is 4P3T, and the pins are in-line. Therefore, it is a 4P3T in-line toggle switch. 4P3T determines that it has 8 pairs of pins, and at the same time, there are two pairs of brackets, which play the role of supporting, fixing and grounding. Widely used in building automation, electronic products.
4. Long actuator top dial type toggle switch
The actuator is 12mm and is located at the top of the switch, so it is a long-actuator top-dial type toggle switch. Widely used in digital audio and video, various instruments / instrumentation equipment.
toggle switch structure
The toggle switch is mainly assembled from the following components after corresponding processing:
1. Iron shell (material: generally iron; treatment process: through nickel electroplating or black pot treatment to prevent oxidation)
2. Plastic handle (Material: generally POM material, if there is a fire retardant, flame retardant and high temperature resistance requirement, PA nylon material is often used. Processing technology: injection molding)
3. Terminals (Material: Phosphor bronze in general; Process: Electroplating silver)
4. Insulation bottom plate (Material: Bakelite; Process: Stamping)
5. Contact chip (material: generally phosphor bronze; processing technology: electroplating silver)
6. Round wave beads (material: generally stainless steel; processing technology: electroplating nickel)
7. Slingshot (Material: Bronze; Process: Stamping)
8. Decorative oil (Material: red oil or green oil, a kind of chemical oil, smeared on the contact part of the terminal and the bottom plate to play a decorative role. Generally, it is required to be non-toxic and environmentally friendly)
Toggle switch performance characteristics
The toggle switch is a new generation of photoelectric switch devices manufactured by integrated circuit technology and SMT surface device technology. It has intelligent functions such as delay, expansion, external synchronization, anti-interference, high reliability, stable working area and self-diagnosis. This novel photoelectric switch is an active photoelectric detection system type electronic switch using pulse modulation. The cold light sources used include infrared light, red light, green light and blue light, etc. Control the state and action of various solids, liquids, transparent bodies, black bodies, soft bodies, and smoke.
Driving waterproof and explosion-proof switch The contact type travel switch has the disadvantages of low response speed, poor accuracy, easy damage to the detected object and short life when contact detection, while the transistor proximity switch has a short operating distance and cannot directly detect non-metallic materials. However, the new photoelectric switch overcomes the above shortcomings, and has small size, multiple functions, long life, high precision, fast response speed, long detection distance and strong resistance to light, electricity and magnetic interference.
Introduction to the variety and mechanical performance specifications of the toggle switch The toggle switch is used to turn the circuit on or off by turning the switch handle, so as to achieve the purpose of switching the circuit. The commonly used types of toggle switches are single-pole double-position, single-pole three-position, double-pole double-position and double-pole three-position, etc., which are generally used in low-voltage circuits and have the characteristics of flexible slider action, stable and reliable performance.
