8H61  The Switch Alarm

"Switch Alarm" will automatically turn on your radio at a pre-selected time to awaken you to music, or to turn on your favorite radio program. It also has a conventional alarm signal which can be used or not, as desired. Simply plug your radio into the receptacle in the case back and set "Switch Alarm" for the time you want to be awakened.

My 8HA61 above (before I sold it). As far as I could tell, the only difference between it and the 8H61 (below right) was the larger time set knob which was really a boon.  Nearly all are going to come with the white knobs with the arrow but the brown ones were on it when I bought it so maybe that was what was going out the door that day.  I'll wager no one has seen one with a black dial (below-right) shown in the dealer catalog but I'm always looking!  The case design is simply a reduced Musalarm.

VERSATILE ALARM CLOCK: You can plug your bedside radio set into this clock and instead of the alarm going off it will turn the radio on at a pre-determinted time. It can also be used to turn on an electric light at any given time but is not intended for use on other household appliances.  It is also a standard type alarm clock having an alarm signal of its own.  This is a product of the Warren Telechron Co. and it is called the "Switch-Alarm."  Sister models are "Musalarm" and "Lite-Call."

Alarm Clocks to Wake the Deaf

The Warren Telechron Company, of Ashland, Mass., manufacturers of well known time-keepers, have recently sent out a questionnaire to ascertain the demand for alarm clocks which will awaken those who cannot hear them. If the results of the survey indicate that a definite need exists, the company will make an effort to have special clocks produced, perhaps before the end of the war. The questionnaire inquires about preferences for spring-wound or electric clocks; estimates as to fair prices; and preferences for different types of "waker-uppers" —flashing lights, vibrators, or very loud alarms. If you need such a clock, or know others who do, you will be rendering a service if you fill in one of these questionnaires. If you did not receive one, ask the company for it. Getting such a product on the market may help somebody to hold his job. 

From the Volta Review July 1944.  Clocks like the Beam Alarm and Switch Alarm might have come out of that survey. Was this just keen market research or an abundance of patiotism?  I say the reason was mostly humanitarian and no one is gonna convince me otherwise!
