Switch Operated By Falling Current TRIZ Cases
- Receptacle GFCI Reverse Wiring Protection and Contact Reliability
An electromagnetic reed switch detects reverse wiring in a receptacle ground fault circuit interrupter, preventing electric shock hazards during installation.
- Circuit Breaker Tripping Mechanism with Integrated Reset
Integrated tripping unit resets automatically during switching rotation, reducing volume while maintaining reliability.
- Symmetrical Input Circuit Interrupter for Reverse Wiring Prevention
A circuit interrupting device with symmetrical inputs detects terminal connections to ensure correct line and load wiring.
- Overcurrent Switching Device Using Magnetic Shape Memory Alloy
A magnetic shape memory alloy expansion unit interrupts an electric circuit by reacting to a generated magnetic field.
- Current Transformer Saturation Compensation for Motor Circuit Protectors
Mathematical models compensate current transformer saturation, extending operating range and reducing material costs.
- Resettable GFCI with Wiring Detection and Lockout
A resettable circuit interrupter detects wiring configuration to prevent reverse connections.
- Power Plug Insertion Plate Sleeve Thermal Protection
An insulating and temperature-resistant insertion plate sleeve prevents plastic body deformation from high temperatures generated by electrical resistance.
- GFCI Locking Mechanism Prevents Faulty Reset
A locking mechanism secures a GFCI movable assembly in the tripped position using a resilient member and blocking member.
- Circuit Breaker Trip Actuator Assembly Orientation
A trip actuator assembly secures a solenoid mechanism within a circuit breaker housing using an interface element.
- Test Button with Stop Contour for Circuit Breaker Safety
A test button integrates a stop contour to actuate the tripping mechanism of an electrical switching device.
