Contact Operating Parts TRIZ Cases

An elastic unit mounted in a base seat cavity pushes contacts to close or open the circuit.

Segmented plate and wire mechanisms transmit force to operate switches from a safe distance, eliminating operator exposure to arc flashes.

Segmented compression coil springs bias the cover toward an opened position, preventing bending damage when pushed closed from one side.

An adapter converts existing rocker switches into toggle levers, resolving the contradiction between limited functionality and high development complexity.

A hand switch actuates a locking device to secure the rotation setting unit, preventing accidental changes during operation.

Nested actuating pins open a monitoring circuit upon unauthorized separation, resolving reliability versus complexity trade-offs in safety switches.

Segmented structural design reduces actuation force requirements while maintaining stability and minimizing wear in magnetic position sensors.

A safety switching device uses pressure-sensitive elements to detect collisions between aircraft components.

Two independent air pressure domes drive separate pneumatic cylinders to activate nurse station alarms and auxiliary devices without electrical arcing risks.

Segmented supporting legs prevent key cap flipping during actuation, maintaining sensitivity in thin keyboards.

A mechanical lockout device inserts a protrusion through an aperture in the housing to control the electronic switching mechanism.

Flexible conductive beams and insulated joints divert lightning currents away from sealing areas, preventing arcing at telescopic mast interfaces.

A modular reset device couples to limit switch heads via universal interface means to ensure simultaneous contact opening and activation.

A key module uses a pivoted scissors structure with sliding shafts to transmit pressing force.

A switch control module integrates a linkage unit and sealing member to rotate an internal shaft through a housing opening.

A rotary switch uses a gear to couple an offset button to a radially nested potentiometer.

Replacing thick rubber sheets with thin flexible films reduces device volume and manufacturing time while maintaining reliable key attachment.

A concentric electrode switch strip uses radial symmetry to detect obstructions without directional constraints.

A steering wheel remote control uses vertically spaced printed circuit boards to isolate switch terminals and enable flexible button layouts.

A pivotable shift lever converts linear rod displacement into rotational movement to actuate a drive switch in powered tools.

A plunger switch assembly uses a two-piece retainer support to form a nesting pocket that securely holds terminal members within defined grooves.

Pressure strips and load cells detect excess weight on a door edge, alerting caregivers via a nurse call system when hanging attempts occur.

An inclined button bottom surface rotates to press the movable section perpendicularly.

Dual injection molding coats wire connections with rubber-like elastic layers, eliminating adhesive processes that increase manufacturing time.

A rotary switch shaft transmits force to a stopper that contacts an outer wall part.
