Abstract

1,016,332. Flashing indicators. MIDGLEY HAMER Ltd. Sept. 7, 1962 [June 9, 1961; July 7, 1961], Nos. 20949/61 and 24684/61. Heading G4Q. In an electric interrupter switch mechanism for operating flashing signal lamps in a motor vehicle and a pilot lamp for indicating whether the flashing signal is operating, the circuits of the signal and pilot lamps are controlled by a switching device operated by a relay whose energizing circuit 10 is controlled by a condenser 9 in parallel with the energizing coil and adapted to be alternately charged and discharged on the closure of a controlling switch 19 so as to bring about the intermittent operation of the signal and pilot lamps. The arrangement is such that automatic quenching of any arc formed between the contacts of the switching device is effected. In one embodiment (Fig. 1) the switch arrangement consists of a two-way switch having a moving contact 1 normally closed with contact 2 connected to the pilot lamp and making connection with contact 3 connected to the indicator lamps when the relay is energized. On closing the operating switch 19 the battery potential is applied to the split relay coil 11 such that currents flow both ways until the condenser 9 is charged. When this is accomplished the currents in the coil cease to cancel and the relay operates to close the indicator lamp circuit and allow the condenser to discharge through the coil 10, holding on the relay. When it is discharged the relay returns to its normal position, closing the pilot lamp circuit, and the sequence repeats. A second embodiment (Fig. 2, not shown) is described, employing only a one-way switch operated by the relay, with the circuit arranged so that the pilot lamp is short-circuited when the relay operates to close the switch, but is energized when the switch is open.
