UNIVERSAL MODULAR STRUCTURES OF SWITCHES Russian patent published in 2019 - IPC H01H13/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, specifically to universal modular structures of switches, such as modular switches, modular control switches, modular button switches intended for distribution of electric energy in alternating and direct current circuits for switching of electric circuits, for signaling and protection of these circuits. Proposed device comprises case with switching device connected with mounting shoe with slots and ledges for connection of detachable contact module. Block of contacts is fixed on a mounting block so that ledges of the block of contacts have coincided with grooves of a mounting shoe. Fixed contacts are located in the housing, screw-terminals are screwed in them, which fix the connected wires.

EFFECT: possibility of replacing contact modules, leaving on-site switching device.
