The CHINT NP2-BJ21 and NP2-BJ33 series are selector switches within the NP2 line, used to control electrical circuits by selecting between different positions.  These switches typically feature a rotary handle or knob. The NP2-BJ21 is a two-position selector switch, while the NP2-BJ33 is a three-position selector switch. They are commonly employed in industrial settings to choose operation modes, control machinery, or direct electrical flow, providing more control options than a standard push button. Features of CHINT NP2-BJ21/NP2-BJ33 Series: Rotary Operation: Allows selection between different circuit states. Durable Metal Construction: Provides robustness for industrial environments. Non-Illuminated: Simple and reliable operation without illumination. Standard Mounting Size: 22mm mounting diameter. Compact Design: Saves space on control panels. Reliable Contacting: Ensures consistent electrical connection.
