Contact Driving Mechanisms TRIZ Cases
- Circuit Breaker Operating Mechanism for Manual-Auto Trip Decoupling
A hook-based operating mechanism decouples button pressing from fault tripping, allowing safe manual and automatic contact switching.
- Switch Operating Mechanism With Dual-Spring Contact Opening
A dual-spring operating mechanism increases moving-static contact opening distance by staged energy storage and release in low-voltage switches.
- Staggered Multi-Contact Contactor for Arc-Limited Switching
A higher-resistance switching contact limits current before the main contact closes, reducing arcing, fusion, and contactor damage.
- Planetary Gear Selector for Compact On-Load Tap Changers
A planetary gear selector replaces separate selector arms to keep on-load tap changers compact while supporting uninterrupted tap switching.
- Vacuum Interrupter Assembly With Hydraulic Damping for Wear Control
Hydraulic damping in the driving rod assembly controls contact motion in both directions, reducing wear and improving switching reliability.
- Switchboard Switch Loading Assembly With Integrated Lever Coupling
An intermediate-position lever coupling combines decoupling, end-of-stroke, and return functions to shrink switchboard loading assemblies.
- On-Load Tap Changer Switching Module With Plate-Separated Contacts
A plate-separated vacuum interrupter and bridge switch cut tap-changer installation space and material use while maintaining insulation reliability.
- Microswitch Tension Spring Assembly with Rotary-Table Position Detection
A four-stage rotary-table process improves microswitch tension spring engagement accuracy and screens out unqualified assemblies.
