A switch assembly for an electricity meter comprising two parts, one of which parts (2) includes a fixed contact (12) and a meter output terminal (13) and the other of which parts (1) includes a moving contact (8) and a meter input terminal (3), the moving contact being coupled to the input terminal via a conductive spring (7) on which it is supported and which serves in use both to carry switch current and to bias the moving contact towards the fixed contact, and via a meter shunt (5) adapted so as to receive in use, sensor conductors so that current supplied via the switch from the input terminal to a consumer via the output terminal can be sensed for measurement purposes. <IMAGE> |
