A fused switch unit is provided with two connecting contacts into which a fuse holder (20) can be inserted in order to hold a fuse link (30) with a head contact (31) and a foot contact (32). A first connecting contact (60) of the fused switch unit (10) can be connected via a controllable interruption contact (80) and by means of a bridging element (81) to a first of the contacts (31) of the fuse link (30). The fuse holder (20) or the fused switch unit (10) has a fuse state indicating device (40) with two contacts (42, 43) for an electrical connection for the connecting contacts (60, 70) of the fused switch unit (15). A first contact (42) of the fuse state indicating device (40) can be connected via an electrically conductive connection (91, 92, 82) directly and exclusively to the bridging element (81), and a second contact (42) of the fuse state indicating device (40) can be connected directly via an electrically conductive connection (50, 51, 52, 53, 71) to the second connecting contact (70) of the fused switch unit (10). This allows a high degree of flexibility for arrangement of the elements. Furthermore, it ensures a high level of operational reliability and safety, and little wear.
