Contact Driving Mechanisms TRIZ Cases
- Bistable Relay Motorized Switch Mechanism
Motorized bistable relay replaces electromagnets with spring-loaded cams to reduce size and power consumption while maintaining fast contact operation.
- Switching Device Holding Mechanism Prevents Premature Contact Movement
A holding mechanism constrains an impeller vane within a predetermined angular range using frictional forces to maintain stable positioning.
- Three-Position Actuator Overrun Prevention via Zeneva Disc
Separate drive shafts and a zeneva disc mechanism prevent overrun faults while eliminating noisy spring collisions.
- Electrical Switch With Linear Fixed Contacts
Linear fixed contact arrangement simplifies cable routing and expands switching capacity within confined spaces.
- GFCI Contact Separation via Torsion Spring Cam Mechanism
A torsion spring and cam mechanism actuate GFCI contacts for independent separation, reducing device volume while maintaining reliable electrical isolation.
- Push-Push Switch Drive Mechanism with Single Spring
A push-button switch drive mechanism uses a single compression spring to provide both elastic return and tilting forces for bistable operation.
- Three-position load isolating switch with segmented current paths
Segmenting the current path into main and secondary circuits reduces vacuum interrupter complexity while maintaining reliable arc extinguishing.
