<p>Security electric switch with a melting member (6) comprises at least one phase unit (1), which is furnished with a casing (3) and connectors (33, 34) placed thereon and adapted for being connected with each disposable phase wire in the electric circuit, as well as at least one neutral unit (2), which is also furnished with a casing (3) and connectors (33, 34) placed thereon and adapted for establishing connection with each disposable neutral wire of the electric circuit, wherein a bearing member (51) together with a melting member (6) inserted therein and furnished with a protrusion (360) adapted to cooperate with said circular guide (36) in the casing (3) is embedded within said casing (3) of the phase unit (1) with the possibility of being pivoted in the circular direction and in its initial position also linearly displaced in the radial direction, while a bearing member (52) without any melting member (6) but also furnished with a protrusion (360) adapted to cooperate with said circular guide (36) in the casing (3) is embedded within said casing (3) of the neutral unit (2) with the possibility of being pivoted in the circular direction and in its initial position linearly displaced in the radial direction, and wherein said casing (3) of each neutral unit (2) is mechanically connectable with a casing (3) of each disposable phase unit (1), which is adapted for establishing an electric circuit in cooperation of said neutral unit (2), where at the same time each bearing member (52) of each neutral unit (2) is in the area of its outside of the casing (3) located end portion (520) mechanically connectable with the outside of the casing (3) located end portion (510) of the bearing member (51) of each disposable phase unit (1), which is adapted for establishing an electric circuit in cooperation of said neutral unit (2), so that each displacing of the bearing member (52) of the neutral unit (2) is feasible only by simultaneously displacing bearing members (51) of each disposable phase units (51).
