SWITCH CLEANER Russian patent published in 2006 - IPC B61L7/08 E01H8/00 

FIELD: railway transport; permanent way; switches.

SUBSTANCE: proposed device contains switch drive 9 connected with operating rod and points, switch drive control unit 10, power interlocking devices 11, switch plus position relay 38 and switch minus position relays 39, closing relay 40 and switch track relay 37, TC-TS (telecontrol - telesignalling) channel equipment of dispatcher interlocking of line and central stations, timer 16 reverse repeater of closing relay of switch electric drive additional control circuits and first, second and common closing relay and opening relay of additional switch electric drive control circuits coupled with equipment of TC-TS channels. First and second scrapers are placed between guide rail and adjoining point being connected with operating tie-rod through connecting couplings and scraper rotation control mechanism 8, and switch electric drive control circuits 23 are fitted in additionally into said mechanism. Cleaning is done by special scrapers placed between guide rails and adjoining switch points connected by their translational and rotary motion control mechanism with operating tie-rod of switch drive.

EFFECT: improved reliability of cleaning of switch at reduced power consumption, cushioning of point-to-guide rail impact at end of switching.
