A toggle switch connects or disconnects a circuit by moving a switch lever, thus switching the circuit. Common types of toggle switches include single-pole double-position, single-pole triple-position, double-pole double-position, and double-pole triple-position switches. They are generally used in low-voltage circuits and feature flexible slider action and stable, reliable performance. Toggle switches are widely used in various instruments/meters, electric toys, fax machines, audio equipment, medical equipment, beauty equipment, and other electronic products.
A toggle switch is mainly assembled from the following components through appropriate processing:
1. Iron shell (Material: generally iron; Processing: nickel plating or blackening to prevent oxidation)
2. Plastic handle (Material: generally POM; PA nylon is often used if fire retardancy and high temperature resistance are required; Processing: injection molding)
3. Terminal (Material: generally phosphor bronze; Processing: silver plating)
4. Insulating base plate (Material: bakelite; Processing: stamping)
5. Contact chip (Material: generally phosphor bronze; Processing: silver plating)
6. Circular ball (Material: generally stainless steel; Processing: nickel plating)
7. Slingshot (Material: bronze; Processing: stamping)
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 purposes. Generally required to be non-toxic and environmentally friendly)
