A connecting device and a low-voltage switching device comprising the same

A connecting device (30) comprises a housing (32) comprising an opening (38) for receiving an electrical conductor, and a tool opening (37) and at least one spring-force clamp connector (S, 31, 32) in said housing (32), comprising a bent leaf spring (S) and a responsive counterpart wall (31), the bending of the leaf spring (S) forming a first leg (33) and a second leg (36), said leaf spring (S) adapted i) to clamp an electrical conductor between said first leg (33) and said counterpart wall (31) and ii) to release said electrical conductor upon being pressed through said tool opening (37) by a pressing tool- The housing (32) further comprises a further opening (39) for receiving a second electrical conductor (40). The leaf spring (S) is adapted, in response to receiving a second electrical conductor (40) through said further opening (39), to allow bending of said second leg (36) and so to clamp said second electrical conductor (40) between said second leg (36) and a second counterpart wall (31). An independent claim for a low-voltage switching device.
