Protective Switch Operating/Release Mechanisms TRIZ Cases
- Switching Device Holding Part Segmentation
Segmenting the holding part from the restoring spring simplifies assembly and boosts reliability in electrical installation switches.
- Thermomagnetic Actuator Thermal Insulation for Switch Response Speed
A thermomagnetic actuator uses thermal insulating rings and guides to direct heat efficiently to the bimetallic disc.
- Remote Triggering Module for Electrical Switches
A remote triggering module integrates into electrical switches using flexible conductive blades and an electromagnet actuator.
- Universal Trip Device Modular Neutral Extension
A universal electronic trip device structure featuring a three-pole block configuration that adapts to four-pole devices via single-pole extensions.
- Retractable Pin Modular Device Assembly
A modular device with a retractable pin enables secure electrical connections between circuit breakers and protective devices.
- Circuit Breaker Trip Device Lever Position Feedback
A trip device manipulation lever returns to an ON position when contacts fuse, providing clear visual state indication.
- Electromagnetic Actuator Secondary Coil Overvoltage Immunity
A secondary coil generates an opposing magnetic field to counteract transient overvoltages in electromagnetic actuators.
- Handle Elevation for Circuit Breaker Assembly
An elevation on the actuating part distinguishes cover types to prevent incorrect installation and reduce production costs.
- Modular Solenoid Actuator for Circuit Breaker Remote Reset
Segmenting the actuator into a replaceable module solves premature solenoid failure, extending device lifespan without increasing size.
- Bent Sheet Metal Yoke Sleeve for Switching Devices
Replacing turned parts with bent sheet metal reduces machining time and material waste while maintaining magnetic field guidance.
- Motor Control Center Shutter Mechanism for Stab Isolation Access
Cam-driven shutter blocks stab isolation portals during conduction, preventing unauthorized access while allowing operation when handles are off.
