Part 3/8:
Consider a retro timer switch from the 1970s, like the Intermatic Time-All. This device features a circular wheel representing a 24-hour period, with movable tabs that correspond to "ON" and "OFF" positions. Users can set their desired times by positioning these tabs along the dial. The simplicity of its mechanics is fascinating: a synchronous motor drives the gear reduction that allows for precision timing, while a manually adjustable switch mechanism completes the connection.
