ABSTRACT:
An alarm clock with a local alarm system including a movement-operated switch, a normally-closed key-operated switch and an audible alarm device connected in series across the power lines. The switch-operating key may be remotely located so as to require the user to leave his bed in order to obtain the key, insert it in the key-operated switch, and turn the key so as to shut off the alarm. The system may include a time delay latching arrangement to prevent immediate latching the key switch open and to require the user to hold the key turned for a predetermined delay period, sufficient to produce wakefulness of the user. A signal lamp shows the delay period to be in effect until the period has been completed, thereby requiring the user to manually hold the key-operated switch open until the lamp becomes extinguished.
