Electronic Mosquito Tennis Racket: This is the product category. It's a handheld device that looks like a miniature tennis racket. The head of the racket contains a three-layer wire mesh. The two outer layers are for safety (usually not electrified), and the middle layer is a high-voltage grid. When a flying insect comes into contact with the middle grid and a secondary conductive mesh, it completes a circuit, and the electrical current instantly kills it.

Yes-O: This is the brand name. Yes-O is a brand that likely specializes in consumer electronics and household goods. They are a less-known brand, and their products are generally positioned at an affordable price point.

YS786: This is the specific model number. Manufacturers use these numbers for product identification and inventory management.

Key Features of a Typical Electric Mosquito Racket:

Rechargeable: Many modern electric rackets are rechargeable. They have a built-in battery and a charging plug that can be inserted directly into a wall socket or charged via a USB cable. This eliminates the need for disposable batteries.

Safety Features:

Protective Grids: The three-layer mesh design is a key safety feature. The outer layers are there to prevent a user from accidentally touching the high-voltage inner grid.

Safety Switch/Button: The racket is not always "on." It usually has a main power switch and a separate activation button that must be held down while swinging the racket to electrify the grid. This prevents accidental shocks.

LED Light: Many models, including the YS786, come with a built-in LED light. This feature is particularly useful for locating and zapping mosquitoes in the dark.
