Abstract
In a battery powered alarm clock, an alarm switching device comprises at least one detecting wheel whose phase is set in accordance with the desired alarm time, at least one detecting switch which is closed when the phase of the time wheel of the clock corresponds to that of the detecting wheel and a printed circuit board having alarm circuitry mounted thereon with at least one land for connecting the alarm circuitry to one pole of the battery. The alarm switching device construction provides solderless connection by at least two battery contact plates for contacting the two poles of the battery. One of the plates provides three electrical contacts including a first contact with one pole of the battery, a second contact with the land on the printed circuit board and a third contact with the detecting switch, whereby the assembly and construction of the clock is greatly simplified.
