Abstract

The electric light installation timer is used to switch the mains supply during low periods of utilisation. It is mainly intended for street lamp operation at the remote locations during lighting-up times. The timer has a synchronous motor (1) and a gear box to give one revolution of its shaft (2) every 24 hours. It also has an electromagnet (3) driving a clutch (8) and a set of cams (4, 1, 4, 2) used to operate a switch (6). This switch (6) operates the lamp (7) through an electronic or electromagnetic relay (11). The timer can be installed inside the lamp fitting and is connected in series with the existing circuit.
