FIELD: electricity.SUBSTANCE: switch design includes at least two structural members and namely a structural member (20) of the switch and a bearing unit (21). The structural member (20) of the switch with a pivot bearing (36) can rotate in the bearing unit (21). The switch design includes a switch (14) with a contact spring (19). In an inactivated closed position (47) of the switch (14) the contact spring (19) adjoins to a contact (18) of the switch (14). Simple design and self-cleaning effect of the switch are reached when the pivot bearing (36) has a twisted section (35) which allows pressing the switch (14) placing it to the activated closed position (37) through the inactivated closed position (47). At that the contact spring (19) slides along the contact (18) between the inactivated closed position (47) and the activated closed position (37).EFFECT: improvement of operational safety and simplification of the design.19 cl, 7 dwg |
