AI Technical Summary
Existing microswitches have trigger rods that are directly connected to the conductive structure. This can easily lead to uneven stress on the conductive structure due to lateral forces or uneven pressing, affecting reliable contact and potentially causing damage. Furthermore, the operation method is limited and cannot meet the needs of applications with frequent operation or space constraints. Microswitches with push-operated handles are prone to fatigue fracture at the connection end under high-frequency use, affecting service life and reliability.
The design adopts a rotating connection between the operating handle and the housing. The rotational motion is converted into the linear motion of the trigger rod through the mounting bracket. The conductive structure is controlled by electrical signals through movable connecting pieces and expansion plates to avoid structural fatigue. Elastic elements and guide grooves are used in the conductive structure to improve stability and accuracy.
It improves the service life of the operating handle, enhances the overall durability and stability of the switch, provides a more flexible operating method, reduces structural fatigue and wear, and extends the service life of the switch.
