OPERATING MECHANISM FOR OPENING AND CLOSING AT LEAST TWO CONTACTS SIMULTANEOUSLY

The invention relates to an operating mechanism for opening and closing at least two contacts simultaneously. This mechanism comprises- a bridge body having an elongate contact surface configured be in contact with the operating rods of the two contacts;- a first reaction arm hinging with one end to a base frame and with the other end to the bridge body;- a second reaction arm hinging with one end to the base frame and with the other end to the bridge body;- a rod mechanism of two links wherein the first ends of the two links are hinging with each other, wherein the second end of one link is hinging with the base frame and the second end of the other link is hinging with the bridging body;- a cam (13) arranged on a shaft (14), wherein the shaft (14) extends parallel to the hinging axes of the rod mechanism (28, 29) and is in operating contact with the hinging axis of the first ends (30) of the two links (28, 29).- a cam arranged on a shaft, wherein the shaft is arranged adjacent to the rod mechanism, wherein the shaft extends parallel to the hinging axes of the rod mechanism and wherein the cam is in operating contact with the hinging axis of the first ends of the two links.
