Flat Torsion Spring for Knob — No name, model Czę002275

Flat torsion spring intended for use with control knobs and rotary handles. Supplied under No name with model Czę002275, this flat torsion spring provides rotational spring force and return action in compact knob assemblies. Its low-profile design fits where axial space is limited and where a flat spring profile is required to engage the knob and shaft interface. Mounting specifics and retention depend on the receiving knob and shaft geometry.

Advantages

The flat construction delivers consistent torsional force in a slim form factor, enabling a low-profile return mechanism for knobs and rotary controls. Because the spring is designed for mechanical engagement with knobs and shafts, it can provide reliable return action and positional detent where required. Its simple geometry makes it suitable for integration in appliance and instrument panels without adding significant height or bulk.

Suitable for

• Control knobs on household appliances (ovens, cooktops, washing machines)
• Instrument and equipment rotary handles
• Panel-mounted controls with limited axial clearance
• Repair or replacement of flat-profile knob spring mechanisms

Key specifications

• Form factor: flat torsion spring suitable for knob engagement
• Function: provides rotational torque and return action
• Profile: low axial height for compact assemblies
• Material: spring-grade metal (steel or similar), corrosion resistance depends on finish
• Compatibility: designed to work with receiving knob and shaft geometries that accept a flat torsion element

How to use

Install the flat torsion spring between the knob and mating shaft or within the knob recess according to the receiving component's alignment features. Ensure the spring's legs or contact points align with the knob's engagement surfaces so that torsional force is transferred correctly when the knob is rotated. Confirm the orientation provides the desired return direction and that the spring is seated without excessive bending or deformation. Final retention may require the knob to be pressed onto the shaft or secured with the original fastener, depending on the assembly design.

Usage recommendations

Verify dimensional fit and rotational direction before final assembly; test in the original knob and shaft combination to ensure correct return force and clearance. Avoid over-bending the spring during installation and inspect for secure seating to prevent slippage. If corrosion resistance is critical, consider confirming the spring finish or selecting a treated alternative.
