Product Description
In a control cabinet, switching between operating modes must be deliberate. The 22mm Plastic Rotary Selector Switch is built for that purpose.
The handle rotates with controlled resistance. Each position locks in with a firm detent. There is no loose travel and no vague alignment. When the operator turns the actuator, the movement is steady and defined. The position is clear both visually and mechanically.
The 1NO+1NC contact structure allows simultaneous control of two independent circuits. One contact closes while the other opens depending on the selected position. This makes it suitable for forward/reverse control, manual/auto selection, or other multi-mode control systems.
The plastic housing provides insulation and resistance to environmental exposure while maintaining lightweight structural strength. The switch is designed to fit directly into a 22mm panel opening, reducing installation time and avoiding panel modification.
The base is made of PA66 material, and the contacts are made of copper base composite points.Longitudinal dense arrangement, small travel, good comfort;
This product is built for systems where switching reliability affects operational continuity.
Switching Structure & Contact Logic
3-Position Maintained Operation
This maintained design ensures that once a mode is selected, it remains active until manually changed. It prevents accidental reset and supports stable system logic.
1NO + 1NC Contact Configuration
One normally open contact
One normally closed contact
Independent circuit control capability
This configuration allows flexible wiring schemes. It supports interlocking logic, directional switching, and safety integration within control circuits.
Mechanical Performance & Feedback
The selector switch is engineered for consistent rotation and clear engagement.
Mechanical Characteristics
Balanced rotational torque
Defined detent positioning
Stable actuator alignment
Designed for repetitive switching cycles
The tactile feedback is firm and controlled. Each position transition is distinct. This reduces operator uncertainty and improves switching accuracy in real working conditions.
Electrical Reliability
Stable electrical performance is critical in control systems. This model supports:
Consistent contact engagement
Reliable circuit transition
Low contact resistance structure
Stable contact alignment under load
When operated within rated electrical conditions, the switch maintains predictable contact performance across repeated cycles. Proper installation ensures long-term reliability.
