(54) Electronic timeswitch


(57) The timeswitch comprises a switch actuated in accordance with a pre-set switching program, by microprocessor controlled circuitry, and a display 10 comprising an analogue time display portion 10a. The analogue portion 10a comprises inner and outer concentric circles of actuable indicia 12, 14. In the running mode of the timeswitch, in one configuration, the indicia 14 of the inner circle are sequentially actuated to represent the hour hand of an analogue clock displaying the actual time. The outer indicia 12 are actuated in groups to represent the, switching program «on» times. In the programming mode, the time indicated by the inner indicia 14 may be manually selected, whereafter the state of the switch at that time may be selected. The outer indicia 12 are actuated in sets to represent the switching program being entered. Other configurations of the timeswitch are possible according to the microprocessor software, and some examples are described.
