Redundant Contact Pairs TRIZ Cases
- In-Line Five-Position Switch With Redundant Circuit Actuation
An in-line five-position switch uses double or triple redundant contacts and snap feedback to improve reliability in compact control spaces.
- Aircraft Engine Oil Level Sensing With Redundant Sensor Ladders
Dual sensor ladders compare magnetic float signals to detect faults and deliver accurate aircraft engine oil level readings during pre-flight checks.
- Leaf Spring Contactor for Self-Cleaning Electrical Switches
A multifunctional elastomeric contactor merges elastic restoring force with sliding contact fingers to self-clean surfaces and maintain reliable switching.
- Switch Assembly Pivot Contact Lever Heat Dissipation
A switch assembly uses a pivot contact lever with an elastic metal plate to stabilize electrical connections.
- Segmented Switch Contact Zones for Railway Vibration
Parallel contact zones with tuned resonance frequencies prevent conduction resistance changes caused by railway vibration.
