Abstract
An electricity meter includes input terminals to which, in use, a main electricity supply is connected, output terminals via which, in use, electricity is fed to a consumer, a switch via which electricity is fed from the input terminals to the output terminals and an indicating device operative to provide an indication of the quantity of electricity fed via the switch to the consumer. The meter is adapted to receive a unit arranged in operative association with the switch so as to effect operation of a switch actuator to open the switch for the purpose of interrupting the supply of electricity to the consumer consequent upon receipt by the unit of a predetermined actuation signal.

An electricity meter comprising:
- input terminals to which in use a mains electricity supply is connected,
- output terminals via which in use electricity is fed to a consumer, and
- a switch via which electricity is fed from the input terminals to the output terminals and metering means operative to provide an indication of the quantity of electricity fed via the switch to the consumer, the meter being adapted to receive a unit arranged in operative association with the switch so as to effect operation of a switch actuator to open the switch for the purpose of interrupting the supply of electricity to the consumer consequent upon receipt by the unit of a predetermined actuation signal,
- wherein the switch actuator forms a part of the unit and is arranged to cooperate mechanically with a switch assembly in the meter of which the switch forms a part, so as to effect operation of the switch consequent upon receipt by the unit of said actuation signal.
