The IMO BC3KN9 is a robust and dependable two-position rotary selector actuator designed for industrial control panels, machinery interfaces and operator stations. As part of the established IMO B3 22 mm control-device range, it provides clear manual selection between two maintained operating positions.
This non-illuminated selector features a black rotary knob, a chrome-finish bezel and a distinctive 120° switching movement. Its maintained action keeps the selector in the chosen position after the operator releases the knob, making it suitable for on/off, mode-selection and alternative function-control duties.
Designed for installation through a 22.5 mm panel aperture, the BC3KN9 provides IP65 front protection for industrial environments. Its modular construction allows compatible IMO connectors and normally open or normally closed contact blocks to be selected separately for the required control circuit.
Rotary selector actuators allow an operator to choose between defined machine functions or control states. Turning the IMO BC3KN9 through its 120° movement operates compatible contact blocks, enabling two-state commands such as on/off, local/remote or manual/automatic operation to be implemented within the control circuit.
The maintained mechanism remains in the selected position until it is deliberately turned again. Combined with its IP65-rated front and modular contact-block arrangement, this makes the BC3KN9 a practical operator-control component for industrial panels and machinery.

The BC3KN9 is used to select between two operating modes or control states in industrial machinery and automation systems.
The BC3KN9 has maintained operation, so the knob remains in the selected position after it is released.
The two selector positions are separated by a 120° operating angle.
The selector actuator is designed for installation in a 22.5 mm mounting hole.
The BC3KN9 is a modular selector actuator; compatible IMO connector and contact-block components are selected separately to create the required electrical contact arrangement.
IMO push-button and selector components are used by panel builders, automation engineers and machinery manufacturers to create clear, durable and dependable operator interfaces for industrial equipment.
