[0002] Electric power meter, also known as electric meter, is a device for measuring electric power consumption, widely used in household, commercial and industrial fields. Electric power meter plays an important role in the electric power system, by real-time monitoring and recording electric power usage, helping electric power companies and users to understand electric energy consumption, electric power billing and energy management.

[0003] Currently, the regulation and control of electric power meter is usually operated through multiple buttons on its front side. These buttons are used to set and adjust various parameters of the electric meter, such as electricity rate, time period setting, fee inquiry, etc. The regulation and control buttons on the existing electric power meter are generally designed as press type, directly exposed to the outside. Although this design is convenient for user operation, it also brings some problems.

[0004] Firstly, the press type regulation and control button is easy to be accidentally touched when the electric box of the electric power meter is opened, which may cause accidental changes to the electric meter settings or interrupt the metering, affecting normal electric power usage and billing. Secondly, the exposed buttons are easily affected by environmental factors such as dust and moisture, which may cause the buttons to malfunction or damage. In addition, accidental touching may cause short circuit or other electrical problems of the internal components of the electric meter, which poses potential safety hazards.

[0005] Therefore, the existing electric power meter has certain deficiencies in the regulation and control mode, and a more secure and reliable regulation and control assembly is needed to avoid the problems caused by accidental touching, improve the safety and reliability of the electric meter.
