Model: KW4A
Internal configuration drawing
Vacuum clearners are an important part of modern household cleaning tools, and wall sensors are one of the key technologies that enable smart vacuum clearner along walls. As a common mechanical switch, KW4A(S) micro switches have the characteristics of small size, high sensitivity, and long service life, and can meet the requirements of wall sensors for vacuum clearner. KW4A(S) micro switches are highly sensitive and stable and can accurately monitor the contact status between the machine and the wall. When the machine is close to the wall, the micro switch can detect the contact signal in time and promptly notify the sensor to adjust accordingly, thereby achieving precise control of the sweeper cleaning along the wall.
