Electric Switches TRIZ Cases

A shared drive source makes selected vehicle panel buttons appear or retract, cutting button clutter while keeping functions accessible.

A pre-assembled carrier holds the switch and electronic units while a heat sink improves cooling, integration, and serviceability in machine tools.

A parallel triac and mechanical switch cuts LED inrush arcing, reducing contact erosion while keeping nominal-current losses low.

Constant-current relay coil control times phase switching near zero crossing to reduce arcing and keep contact fault energy low.

Open-cell metal foam at the arc chamber outlet cools and slows hot gases, reducing flame emission, shock waves, and assembly complexity.

Opposite-facing solenoids in paired contactor assemblies resist mechanical impulse disturbances and prevent unintended high-voltage power flow.

An oblong N-pole socket delays shaft engagement so remote opening trips L first and fully disconnects N for safer maintenance.

Magnetically coupled coils let one supervision relay track trip circuit health in pre-close and post-close states while avoiding false alarms.

A threaded fixing disk integrates microswitch mounting and sealing to simplify membrane pressure switch assembly and lower part count.

A pushrod moves the busbar to clamp or release a fuse without nuts or bolts, saving space and reducing installation time in pre-fuse boxes.

Pulsed short-circuit current with hysteresis control lets downstream mechanical breakers clear faults before the solid-state breaker trips.

A spring-biased pin and toggle mechanism cuts handle effort between ON, OFF, and TRIP positions while maintaining reliable latch engagement.

A relay control profile uses load data, firing-angle adjustment, and coil overvoltage/current control to stabilize switching timing and reduce torque oscillations.

Switchable steering wheel displays let one input handle multiple functions, reducing scan area while preserving intuitive operation.

A separate magnet holding member and wall structure isolate magnet vibration from the fixed terminal to reduce relay malfunction and preserve arc breaking.

A folded insulating cover with an extension wall separates switch jaws to prevent contact, momentary switching, and meter errors.

A microcontroller measures relay switching delay and corrects trigger timing at zero crossing to reduce arcing and extend contact life.

An integrated holder-casing guides the slider with double support, cutting tolerance buildup and stabilizing multi-directional switch movement.

An elastic fixing member and adhesive stabilize relay terminals in thermosetting resin bases without press-fit cracking or resin waste.

Resin sealing around surface-mounted lead frame elements blocks moisture and sulfide gases, protecting solder joints in switch assemblies.

Arc-triggered semiconductor bypass commutates DC current away from breaker contacts, cutting wear while preserving galvanic isolation.

A partitioned gas path vents hot arc gas away from relay contacts, lowering arc re-ignition risk at higher load capacity.

Opposed magnet polarities route DC relay arcs away from the center region regardless of current direction, protecting internal members.

Segmented elastic-film keyswitches under a flexible display improve tactile feedback and prevent adjacent key activation in virtual keyboards.

A processor-controlled test switch automates passenger conveyor safety chain checks by simulating switch opening and detecting faults remotely.
