FIELD: electrical engineering.
SUBSTANCE: switching unit of the switch consists of a fixed contact element electrically connected to the coil of the interrupting unit; coil is electrically connected to the first contact terminal on the switch body; fixed contact element is located in the above housing outside the interrupting unit, on the side facing the seat. Movable contact element located inside switch housing, is located adjacent to the fixed contact element and is electrically connected to the other connecting terminal on the switch body. Movable contact element is installed with possibility of rotation in the support formed on the free end section of the cantilever rod in the area located in front of the needle of the interrupting unit, and is mechanically and electrically connected to the second connection terminal, so that movable contact element is pressed in direction of fixed contact element by means of spring and can also move in the opposite direction, i.e. from the fixed contact element, overcoming the resistance of said spring, when the switching element turns under the action of the needle.
EFFECT: simplifying the design of the emergency electric switch and improving its reliability.
