Abstract
1446374 Electronic watches AMERICAN MICROSYSTEMS Inc 26 June 1974 [17 Oct 1973] 28467/75 Heading G3T [Also in Division H1] In an electronic watch having a battery (38), Figs. 3 and 4 (not shown), a voltage step-up coil (44), and a circuit board (20) for driving a display unit (14), e.g. of liquid crystal type, under control of a crystal oscillator (42), a switch 18 for setting the display comprises a rotatable actuator disc 70 in a shallow cup-shaped housing which is located in the front wall or rear cover 16 of the watch case. The disc can be moved by means of a coin inserted in slot 74 to one of four positions to set the hours, set the minutes, hold the displayed time, or for normal running. As shown the housing is attached to the cover 16 by adhesive 64 but it may be formed integrally with the cover Fig. 9 (not shown) Several switch contact and terminal arrangements are described, but as shown the disc carries a contact member 78 with portions 84 which engage the housing and form grounding contacts, and with portions 80, 82 which can contact terminal areas 92, 94 depending on the disc's position. These areas are carried on an insulating sheet 90 and connected via leads 46, 48 to the watch circuitry. In one alternative arrangement contact is only made when the actuator disc is axially depressed against a resilient ring (140), Fig. 11 (not shown). Sealing gasket 88 is of p.t.f.e. to minimize triction.
