FIELD: electricity.SUBSTANCE: switching mechanism is purposed for installation at the central hole (5a) of the frame (5); as it is fixed by clamps (7) to back plate (6) it is integrated into a submerged unit of the electrical device. The mechanism consists of a body (1) with inside electrical contacts and cover (2) which is fixed at the above body (1), and in the upper rectangular aperture of the body there is swinging lever (3). Rotary movement of the lever (3) induces movement of rotary contact (21) inside the body (1). The lever (3) is rotated in case of activation of the component (4) in external actuating device fixed to the lever (3) by protrusions (18) at its lower side inserted into ribbed holes (17) in the upper part of the lever (3). Lateral sides of the cover (2) have guides (8) for positioning on top of contacts (9) located at external sides of the body (1), which are aligned by vertical flanges (10) thus ensuring installation and connection of the cover (2) to the body (1). Two ends of the cover (2) have grips (14) which provide possibility of the body (1) and cover (2) fixing to back plate (6).EFFECT: rapid changing of the switching mechanism configuration without necessity of changes in components of the submerged unit.5 cl, 19 dwg |
