Illumination, changing advertisements by controlling; actuating.-In electric letter signs which appear to change in size by sets of lamps being illuminated in succession the control switches are so arranged that the set of lamps forming a letter of any one size is not extinguished till after the adjacent set of lamps has been lit. Fig 2. shows contact-makers 6 reciprocated by cams 9 on a rotating shaft 8, the parts being dimensioned so that contact with one set of lamps 2 is not broken till after contact with the next set is made. Fig. 10 shows a rotary switch controlling the lamps of the letter 0, the switch contacts being formed by surrounding a metal cylinder 14 with a sleeve 16 of fibre or other insulating material having suitable perforations a-g. Coloured lamps may be employed and may give the effect of a shadow on one side of the letters.
