notes: label: Description (Brief)
content: Marked: "Signal / Menominee, Michigan". Unit is an antenna change-over switch operated by a large knob. All contact members are mounted on opposite sides of a vertical Formica support. Binding post terminals connect to external circuit. The closing of the switch in the sending position also closes the power circuit which starts the rotary gap motor. On throwing the switch to receiving position, the power is first cut off, the aerial drained of accumulated charge, and the receiving circuit closed. Original price $8.50. Reference: Signal Electric Mfg. Co. Catalog, "High Class Wireless Apparatus," (1922), page 17. Unit restored in 1963.
