Switches With Electrothermal Opening TRIZ Cases
- Rotary Switch With Integral Bimetal Overcurrent Protection
A bimetal element built into a rotary switch trips and resets overcurrent protection while cutting wiring complexity, voltage drop, and cost.
- Rotary Switch With Integral Bimetal Overcurrent Protection
A bimetal element built into a rotary switch trips on excess current, cutting wiring complexity, space use, and voltage drop.
- Stacked Bimetal Trip Unit for Miniature Circuit Breaker Width Reduction
Front-to-back stacked bimetal elements preserve trip ratings and flexibility, enabling a compact miniature circuit breaker design.
- Thermal Overload Relay Reversing Mechanism Wear Stability
Extracting the temperature compensation bimetal from the adjusting link eliminates support shaft wear, maintaining a constant reversing operation point.
- Safety Switch Rocker Stabilization for Circuit Stability
A resilient member stabilizes the rocker to prevent unexpected reconnection caused by bimetal strip recovery.
- Fusible Switching Disconnect Modules Prevent Arcing
A fusible switching disconnect module uses a rotatable fuse cover and switch actuator to enable safe circuit operation.
- Bi-directional Thermal Calibration of Circuit Breaker Frame
Rotating a forked tool deforms the elongated slot in the circuit breaker frame to adjust the bimetal assembly angle and resolve inconsistent thermal trip times.
- Circuit Breaker Lever Reducing Friction Between Bimetal Strip and Button
An intermediary lever with a smooth surface reduces friction between the bimetal strip and button, enabling timely current interruption.
- Circuit Breaker Armature Offset for Arc Splatter Resistance
Offset structure prevents tack welding from arc splatter, ensuring reliable circuit breaker tripping.
