Abstract
A time switch programming system of modular construction comprises a plurality of modules each of which is independently operable and programmable to give a respective switching programme, and the modules are functionally connectable by electric or electronic means only. The connections which can be established between the modules are logical linkages, and each module has an independent control means. There is thus no mechanical driving connection between modules. Figure 4 shows modules 19 having cable connections 37 and levers 35 for selecting the desired logic connections between modules. These modules are respectively provided with switching discs in the form of a one hour disc 39, a twenty-four hour disc 40, and a one week disc 41. A further module 53 provides a temperature control function. <IMAGE>
