Connectors are used for easy connection of installation elements. Most often they are built for 250V and 6A. Due to the construction, they are divided into lever, rotary or keyboard (the most typical). Currently, the choice of connectors allows you to find and match them to any interior. The following types of connectors can be distinguished: single (bi-state, works within a single circuit), bipolar (two-state, operates within two circuits), stair switch (combined in pairs, in the case of a larger number of switches required, cross switches are inserted between the stair switches - each switch allows switching on or off), candlesticks (double-stand, designed for chandeliers equipped with several sections), shutter (tri-state, up-stop-down type).
