[0002] Rocker switches are also called rocker switches. They are commonly used in small, high-capacity power switches such as home appliances or office equipment. Their contacts are divided into single-pole single-throw and double-pole double-throw. Some switches also have indicator lights.
[0003] The boat-type switch includes a housing and a button movably arranged on the housing. The button is boat-shaped, and the pressing force required to start or close the switch is relatively large. Since the button switches in a seesaw-like state, a large gap is left between the button and the housing, which makes it easy for water vapor and dust to accumulate in the gap. After the button is pressed, the dust and water vapor easily enter the housing along with the button, causing damage to the boat-type switch and affecting its normal use. Summary of the invention
[0004] In view of the existing rocker switch, there is a large gap between the button and the shell, which makes it easy for water vapor and dust to accumulate in the gap. After the button is pressed, the water vapor and dust enter the switch together with the button, affecting the normal use of the switch. The following utility model is proposed:
[0005] A waterproof and dustproof rocker switch comprises a shell and a rocker button movably mounted on the shell, wherein a mounting frame located on the shell is arranged around the rocker button, a gap is left between the mounting frame and the rocker button, a first indicator mark is arranged on the rocker button, a waterproof and dustproof cover which completely covers the gap is fitted on the mounting frame, two mounting holes are arranged on the waterproof and dustproof cover, a first key and a second key are movably mounted in the mounting holes, a limiting plate located inside the waterproof and dustproof cover is arranged on the first key and the second key to prevent the keys from detaching from the waterproof and dustproof cover, the first key and the second key are located at two ends of the rocker button, and after being pressed, the two ends of the rocker switch are pushed inwards respectively to start or close the rocker switch.
[0006] Furthermore, the boat-shaped button is provided with a curved surface, and a curved pressing block matching the curved surface is provided on one side of the bottom of the limiting plate, and the curved pressing block facilitates pressing the boat-shaped button.
[0007] Furthermore, the waterproof and dustproof cover is provided with a mounting plate extending in all directions, the mounting plate and the mounting frame are provided with matching fixing holes, and threaded fasteners for fixing and connecting the shell and the waterproof and dustproof cover are threadedly connected in the fixing holes.
[0008] Furthermore, a sponge strip is provided at the inner opening of the mounting hole, which fits around the first button and the second button. When the first button and the second button are pressed inwardly, the sponge will enter the waterproof and dustproof cover together with the two buttons to absorb water vapor and dust.
[0009] Furthermore, second indicator marks of different shapes are provided on the outer sides of the first button and the second button to indicate the current state of the rocker switch.
[0010] The utility model proposes a waterproof and dustproof rocker-shaped switch, which has the beneficial effect that a waterproof and dustproof cover is installed on the shell, and the waterproof and dustproof cover greatly reduces the entry of water vapor and dust into the gap between the shell and the rocker-shaped button, reduces the possibility of damage to the rocker-shaped switch due to the entry of water vapor and dust, and improves the reliability and stability of the rocker-shaped switch during use.
