Title: Time controlled switching arrangement for two timer radio receiver

Abstract: A radio receiver is provided having a selectively tunable tuner section and a second tuner section which may be preset to receive the signal transmitted from a single transmitting station. A single output amplifier (including intermediate frequency and audio frequency) is included which is connected to a loud speaker. The first selectively tunable tuner may be connected to the amplifier either by a manually actuated switch or by a clock controlled timer actuated switch through a two position snooze switch. The preset tuner is connected to a timer controlled switch and through the snooze switch to the amplifier. When the snooze switch is turned on, it is not possible to connect the first tuner to the amplifier, but the second tuner is connected provided the timer has not opened the second tuner circuit.
