Contact Operating Parts TRIZ Cases
- Multi-pole Switch-Fuse Arrangement with Lever Mechanism
A multi-pole switch-fuse arrangement uses a spring-loaded lever mechanism to transfer motion from a single switching lever to multiple drive rods.
- Flipper Mechanism for Reliable Electrical Contact in Switching Devices
A U-shaped flipper mechanism pivots to establish electrical contact with terminals inside a housing.
- Dual-Sided Liquid Leak Sensor with Conductive Gap Detection
A portable sensor detects conductive liquids using electrically conductive members separated by a gap that bridges upon contact.
- Switch Device Sequential Operation Pusher Height
A switch device uses a tall pusher to transfer operating force from a knob to sequential manual and automatic switches.
- Removable Push Button Switch With Automatic Contact Opening
A removable push button switch uses a rotatable lever and spring to open contacts when the switch portion separates from the operation portion.
- Rotary Switch Assembly for Pivotable Vehicle Display
A rotor and contactor bridge electrical contacts to control power based on rotational position.
- Keyboard Key Structure with Protective Frame
A keyboard key structure uses a protective frame to secure internal components.
- Rotating Latch Switch Cover Prevents Pin Damage
A rotatable latch encapsulates a switch to prevent accidental activation, eliminating connector pin damage from wire disconnection.
- Keyswitch Cover Detection Eliminates Hall IC Cost
An actuator compresses a keyswitch rubber spring to detect cover status, eliminating expensive hall ICs and precise positioning requirements.
- Keyboard Keycap Elastic Arm Retention Mechanism
Elastic arm constrains extension portion against limiting surface to prevent accidental detachment while maintaining smooth actuation.
- Switchgear Pole Shaft Angle Diagnosis
Diagnosing mechanical wear and energy loss in switchgear drive mechanisms by comparing measured pole shaft rotation angles against initial operating references.
- Rotary Paddle Level Switch Clutch Design for Damage Protection
A resilient clip in the clutch disconnects the transmission shaft from the driving unit when excessive force acts on the propeller.
- Push-Button Switch Lock Lever Mechanism for Mounting Verification
A push-button switch lock lever unit uses a movement regulating portion to verify proper mounting alignment before locking.
- Bistable LCD Reset via Mechanical Pressure in Circuit Breakers
A bistable liquid crystal display module uses a pressure mechanism linked to the actuating handle to update visual information without auxiliary power.
- Spring-Cushioned Bridge for Fused Switch Handle Actuation
A spring-loaded mechanical bridge transmits actuation force to an electrical switch handle while absorbing excess energy from the drive mechanism.
- Keyboard Key Structure Dual Signal Generation Mechanism
A keyboard key structure uses a segmented connecting member to trigger separate optical and membrane switches during downward travel.
- Switching Device Off-Position Locking Mechanism
A switching device uses a locking plate to constrain handle shaft rotation at the off position.
- Multiple State Switch Assembly with Stacked Disc Contacts
Stacked convex disc contacts provide distinct tactile feedback while maintaining mechanical stability in a compact design.
- Ergonomic Electric Deadman Switch with Modular Cord Assembly
A modular electric deadman switch uses a wrist-hinged lever and molded cord assembly to simplify manufacturing.
