Abstract

Two pressure tight spaces (13,14) are provided in the second space (14) there being a moving and a fixed contact (31,32). The moving contact (31) is pressable from the safety insert (16) after pressing the first space (13) against the fixed contact (32) for closing the contacts. Between the two spaces (13,14) a moving transmission part (30) transfers the motion of the safety insert onto the moving contact piece (31). Under the formation of a sufficient air gap the moving contact piece passes through a passage-hole (15) between the two spaces. The two spaces (13,14) are separated by a wall (12) which includes the passage hole (15) for a bolt (30) serving as a transmission part.
