FIELD: electric communication. SUBSTANCE: side walls of housing are equipped with opposite grooves, which length is greater than diameter of lever axle journals which are mounted in said grooves. In addition base of housing carries stationary contacts. Central stationary contacts are designed as support. Mobile contacts, which are mounted on stationary ones for free movement, are designed as plates with projections. Driving lever which is mounted in housing using journals has return spring which is located on side which is opposite to its pressing side and is connected to housing cover. Driving lever is equipped with projections which interact with projections of mobile contacts. EFFECT: increased functional capabilities. 7 dwg
