Relay Switch Mechanical Locking Device

The patent divides the force generation function into two separate mechanisms: a spring mechanism that provides continuous mechanical contact pressure, and a coil former that only provides magnetic attraction force during switching transitions. This segmentation allows the coil to be much smaller since it no longer needs to maintain continuous high force, while the spring handles the sustained contact pressure requirement.

The patent implements a dynamic force distribution system where the spring provides static baseline contact pressure and the coil provides dynamic supplemental force only when needed during switching operations. The rocker mechanism dynamically transitions between spring-loaded contact and coil-assisted contact states, optimizing force delivery while minimizing energy consumption and component size.

The patent employs periodic coil activation only during switching transitions rather than continuous operation. The spring mechanism maintains contact pressure during steady states without energy consumption, while the coil is activated periodically only when state changes are required, dramatically reducing overall energy consumption while maintaining contact reliability.

The spring mechanism serves itself to maintain continuous contact pressure without requiring external energy input or control systems. The system uses the inherent elastic potential energy stored in the spring to provide sustained force, eliminating the need for continuous electrical power to maintain contact pressure.

The patent segments the force provision function between passive mechanical spring elements and active electromagnetic coil, allowing the coil to be minimized in size since it only needs to provide transient assistance during switching. The spring handles the bulk of the force requirement, enabling use of smaller amounts of expensive electromagnetic materials.

The patent changes the operational parameters of the coil from continuous high-force generation to transient low-force assistance. This parameter change allows dramatic reduction in coil dimensions and material usage while maintaining switching performance, as the coil only needs to provide enough force to initiate or assist the switching action rather than sustain the entire contact pressure.
