Abstract
Alarm clock for the deaf, essentially characterized by being constituted from a conventional clock-alarm, which incorporates internally a normally open electrical contact and in combination with the corresponding preindicator needle of the alarm clock of the alarm clock itself, in such a way that said contact is connected on the one hand to a plug for its connection to a power supply line, while on the other hand it is connected to an electromagnetic relay that gives way to the current that reaches a producing element of flashing lights as a flash, so that when the hour hand of the clock indicates the pre-set time of the alarm, the contact closes and the electric current activates the relay, which will give way at intervals, conveniently fixed, to the corresponding producer element of the light flashes.
