Electric Switches TRIZ Cases

A multiposition switch uses a rotatable routing subassembly to connect electrical paths between contact members for precise signal switching.

A permanent magnet positioned adjacent to the air gap aligns its magnetic flux with the coil field to enhance attractive force on the movable iron core.

A pressure switch uses a dedicated positioning means to hold the transmission element at an intermediate position between switching states.

A passive wireless switch uses a UWB transponder to transmit pulses via generated power, avoiding multipath interference and sensor collisions.

Optical coupling replaces mechanical links in a switch assembly, preventing dust accumulation that increases triggering force and degrades reliability.

A miniature circuit breaker uses a button-driven indicating apparatus to visually display the switching-on state through an observation window.

Electronic sensing of bypass switch opening prevents arc re-ignition and reduces IGBT load during short-circuit interruption.

A processor detects contactor type via current flow to configure drive ends for bistable or normally closed units.

Segmented terminal blocks utilize lateral and front faces to expand connection versatility without increasing device complexity or size.

Permanent magnets generate radial fields that displace arcs toward electrodes, ensuring reliable breaking across all current levels.

A rotatable knob interface detects shift via capacitive coupling between a conductive region and sensor electrodes.

An electromagnetic relay uses a metal plate cooling member to extinguish flames in a flat passage, preventing combustible gas ignition.

A frame assembly uses posts interferentially engaged in fixing holes to secure push buttons via elastic connectors.

A unitary cut-off block channels arcs via a metal deflector, preventing contact erosion and enhancing dielectric withstand.

An insulated lockout device uses a telescopic arm to access elevated switches without ladders, preventing unauthorized lever movement via spring-biased locking.

Lateral projections absorb stress on the plate spring, preventing cracks and extending service life.

Integrating contacts and triggers on one arm eliminates separate circuit boards, resolving space constraints while minimizing rattling noise.

A U-shaped fixing cover prevents rubber seals from sagging into housing openings, resolving durability issues in electric power tool switches.

A switch spacer with a pre-formed raised portion offsets adhesive sag, preventing contact point recess and unintended activation.

Two-part key switch housing integrates a rear wall locking projection for snap-in assembly.

A linear actuator uses a permanent magnet to lock the moving body in its first position without continuous power.

Overmolding distinct plastic materials manages temperature variations across switch regions, reducing costs while maintaining reliability.
