摘要: In an improved digital timepiece having a chronometric display in which timing means provides signals thereto, includes first condition responsive to enabling signal for activating the provide from signal, improvement comprises electronic human touch providing signal. The resistive sensitive voltage divider switch impedance path ground response thereof, and second initially being provided. Delay are operatively connected between output input is provision of maintaining as predetermined delay interval while still ground, thereafter changing different provided revert its initial deactivates display. Instead touch, he can have controlled sensitivity so be solely conductive less than at water substantially with such instance comprising least pair spaced apart touchable power source whereby insensitive conductively bridgeable contaminants equal or greater conductive.
