FIELD: electricity.
SUBSTANCE: invention is attributed to the field of electric engineering in particular: to electric snap-action switches and interchanging switches intended to be used in relay sensors (signaling devices) for automated systems of control, protection and signaling. Snap-action interchanging switch contains insulating base 1 with terminals. Elastic plate 4 with contacts 5, 6 is attached to terminal 2 via bracket 3. Contact 8 of screw 9 with contact 10 is attached to the other terminal. Actuating arm 11 connected with cylindrical spring (12) is installed in knife-edge bearings of bracket 3. Intermediate lever (13) with blade A is installed on elastic plate (4) via knife-edge bearings. The other end of cylindrical spring is attached to blade A.
EFFECT: providing possibility to regulate separately differential stroke and differential force (of contact pressing).
