SWITCHING DEVICE Russian patent published in 2022 - IPC H01H3/46 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and is intended for switching electrical circuits for signaling, power supply and control when changing the position of the drive element of the microswitch. The device comprises a housing, a switching mechanism with drive elements, made in the form of at least two microswitches fixedly fixed inside the switching device housing, a lever, one end of which is hinged on the switching device housing, and the other interacts with the contact surface, and a contact assembly with a spring, acting on the drive elements of the microswitches in the process of moving the lever from the initial position to the final position. The lever contains a stop with a spherical surface, while the contact assembly is designed to ensure synchronous movement of the drive elements of the microswitches by the amount of the direct stroke before switching the contacts during the movement of the lever and is made in the form of a board with adjusting bolts installed on it or a board with adjusting bolts installed on racks, and in the central part of the board there is a rod with a cylindrical compression spring, which is pivotally connected to the lever.

EFFECT: simplifying the design and increasing its reliability of the switching device.
