This switch, however, it will be observed, does not
affect the clock circuit. Thus at any time the
unit may be turned oil’ and rendered inoperative
without throwing the clock out of time and then
whenever desired, the unit can be cut back into
service by simply closing switch 258. A condenser
is indicated at 226, for preventing sparking across
the breaker points i it, i it, of the timer and this
same condenser may be connected as indicated at
the current supply ring iii. The No. l magnet
thereby energized will close circuits, as before de

the present disclosure the keys élii in the upper

vent operation of the set at such time. The "A"
position of the wave band selecting keys, as above
pointed out, might be for broadcast, short wave,
frequency modulation, television or the like, which
would mean that in this particular example the
‘stations. say in the broadcast (A) band, would be
“03.” The setting of the keys Mi to other wave
band positions and the keys 3,9 to different station
selecting positions would assure that some station
