The contact keys are easily adhered to foreign objects during the user's contact process, making it difficult for users to easily press, toggle or touch the contact keys to control the switch, which not only affects the sensitivity of the keys, the service life of the keys, and even causes wear and tear. The device is not functioning properly.
