8. Decorative oil (Material: red oil or green oil, a kind of chemical oil, applied to the contact part of the terminal and the bottom plate to play a decorative role. Generally non-toxic and environmentally friendly)

II. Types

Toggle switches are divided into small current toggle switches and large current toggle switches. Small current toggle switches are commonly used in electronic toys and digital communications. Large currents are generally used in electrical appliances, machinery, etc.

Large current sealed toggle switch

Small current sealed toggle switch

1. Large current sealed toggle switch

Its rated current is as high as 5A, and it is sealed with epoxy resin, so it is a large current sealed toggle switch. There are various terminal forms, the contact materials are silver-plated and gold, and the switch functions are diverse. Therefore, there are many types of subdivisions.
