Abstract
Abstract A battery operated quartz crystal controlled alarm clock includes a single printed circuit board having a quartz crystal controlled oscillator and an oscillator controlled drive circuit mounted directly on the single printed circuit board. Additional components as for example a time display unit, an alarm signal source, a disconnect switch for the alarm signal source and one or more batteries are all arranged directly on the same circuit board with direct electrical contact being established between the components and the conductive areas plated on the circuit board. The release spring of an electro-mechanical movement is mounted on the conductor side of the circuit board and serves to establish electrical contact between two conductive areas of the circuit board to complete an electrical circuit for energizing the alarm signal source. The movement is mounted on the opposite side of the printed circuit board and communicates with the release spring through an aperture formed in the printed circuit board. All of the electrical connections are designed to substantially reduce the number of connecting members and the number of soldering operations required to produce the clock.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
193 words
In an electric clock having a printed circuit board with a plurality of conductive areas plated thereon for interconnecting an electromechanical movement mounted on the printed circuit board with a group of modules and for interconnecting the modules, each module having at least one electric terminal, said group comprising a quartz controlled electric oscillator, a drive circuit controlled by the oscillator, an alarm signal source, an alarm release switch operated by the movement for closing the circuit of said alarm signal source, contacts of a manually operated alarm stop switch for breaking said circuit and a battery also having terminals, each of said modules and said battery being arranged on said printed circuit board with at least one of said terminals of each module and battery being in direct contact with selected ones of said conductive areas, with said alarm stop switch comprising a manually operated conductive member slidably contacting said printed circuit board, said conductive member being movable to a first position in direct contact with two of said conductive areas and to a second position out of contact with said areas for selectively electrically connecting and disconnecting said two conductive areas.
