The Norelco 1290X has a pressure sensitive switch that only works when the shaver is awake. Any movement of the shaver causes concentric circles to appear around the on/off switch and allows it to work.
When the shaver is constantly moved while off it enters what is called the "travel lock". The concentric circles no longer appear on movement. A little lock appears instead. The shaver is turned on as usual. It seems that the only purpose of the "travel lock" is to replace the concentric circles with a lock symbol therefore maybe saving a little power. There is no real lock. Why is it called a travel lock?
