Abstract

PURPOSE:To enable the position of an external operating button for lamp flickering to be disposed in the 2 or 4 o'clock position of the watch by crossing the wiring patterns of a lamp switch circuit and an IC chip on a circuit substrate. CONSTITUTION:When the external operating button of an external case conducting to the + electrode of a battery 8 contacts the switch terminals 1a, 1b, 1c of a lead frame 1, switching operation takes place. A lamp 7 is mounted to the specified pattern of the lead frame 1 and the wiring pattern 1d thereof is disposed across an IC chip 4 and is extended to the position 1a opposing to the external operating button in the 2 o'clock position of the watch. As a result of this, the limitation of the external operating button for lamp flickering in the 8 or 11 o'clock as with conventional watches is improved and it may be disposed in the 2 or 4 o'clock position.
