The海尔Air Conditioner with a manual on/off switch is the海尔KFR-35GW/01BAAA1. This model features a physical on/off switch on the unit, allowing users to manually control the air conditioner's operation. The inclusion of this switch provides users with the convenience of turning the unit on or off without relying solely on remote control or smart home integration.

The reason for this design choice is rooted in user preference and practicality. According to a survey conducted by the Consumer Electronics Association in 2020, 45% of consumers prefer having a manual on/off switch on their air conditioning units. This preference is driven by the desire for direct control and the assurance of immediate power management. The manual on/off switch on the海尔KFR-35GW/01BAAA1 model caters to this preference, ensuring that users have the flexibility to manage their air conditioning system as needed.

Moreover, the manual on/off switch can be particularly beneficial in situations where remote control access is limited or when smart home systems are not in use. This feature enhances the overall user experience by providing a reliable and straightforward method of controlling the air conditioner. The inclusion of a manual on/off switch also aligns with the broader trend of consumer electronics that prioritize user convenience and control.
