The button element is intended for remote control of electric drives of machines and mechanisms in mobile and stationary plants, as well as for signaling associated with the specified electric drives or other electrical devices for the domestic market and for export.

Buttons are intended for integration into group I and II explosionproof electrical equipment


  • Buttons KN-BKV are instantaneous switching elements, whose proper actuation time is not more than 0.04 s.
  • The possibility to manufacture with various groups of contacts: 1NO+1NC or 2NO or 2NC.


Blocks BKV-1 and BKV-2 are used as a switching device. The block is made with explosion protection type “explosionproof enclosure” and protection type “е” and has single explosion protection marking ExdeIU/ExdeIICU.

Buttons used in electrical equipment and groups are used in electric circuits of alternating current with frequency 50–60 Hz, voltage up to 660 V and in direct current circuits with voltage of 110 V with nominal current of 16 A.

Buttons used in group II electrical equipment are used in alternating current circuits with frequency of 50–60 Hz and voltage up to 660 V for area 1 and up to 380 V for area 2, direct current circuits with voltage up to 440 V for area 1 and up to 220 V for area 2 with nominal current of 16 A.
