Heating/Cooling Contact Switches TRIZ Cases
- Hot Water Cylinder Thermostat With Thermal Fuse and Relay Failsafe
See how a thermal fuse and electromagnetic relay provide independent failsafe disconnection for
- Dual-Actuator Contact Control for Liquid Heater Overheat Protection
See how a solenoid and bimetallic actuator share one contact set to eliminate steam ducting and
- Modular Thermal Fuse Assembly for Accurate Appliance Heat Cutoff
A common housing replaces the thermal fuse and temperature sensor together, improving heat detection accuracy and reducing repeat appliance service calls.
- PCM Switch Equalization for Uniform Off-State Electric Field
Varying impedance coupling equalizes the off-state electric field in PCM switches, preventing recrystallization and improving voltage handling.
- Arc-Interrupter Fuse Structure for Compact High-Current Breaking
A spring-biased arc interrupter and low-melting insert help a high-current fuse break faults with less arcing, lower resistance, and smaller size.
- Phase Change Switch Impedance Equalization for Off-State Voltage
Varying impedance coupling smooths the off-state electric field in a phase change switch, limiting recrystallization and raising RF voltage handling.
