Re: Cruise Control Setting Question
From an electro/mechanical perspective there seems to be no ill-effects based on other's experience.
But I would like to lay out why manufacturers have implemented the CC in this manner.
Having the on/off switch in addition to the set switch is what is referred to as two-step commanding or arm/fire implementation. Why is this used on CC? It is a system that can engage the throttle. Obviously, in some situations this could be very hazardous if unexpected or unintended. The additional level of interaction is intended to protect against unintended engagement of the system. So it is "unsafe" if a rider leaves the system ON? Probably not immediately so since applying either the brake lever or pedal, pulling the clutch lever or sliding the switch to OFF would all disengage the system.
While all of us would say it is highly unlikely we would reach over and unintentionally or unknowingly engage the CC button, leaving the system ON does defeat one level of inadvertent engagement. Consider if the SET switch were to fail shorted for whatever reason (yes, never heard of it happening and switches at rest do not tend to fail closed on their own, but without looking at the detailed design I could not say that is not a credible failure).
That said, like all things: life is a balance of risks. A failure of the CC that engages the throttle inadvertently is so low, it's probably not anything we would ever have to worry about. But the on/off switch is the belt-and-suspenders implementation to preclude that from occurring. Probably more a manufacturer's CYA more than it would ever be needed. (I can imagine a few years ago Toyota looked deeply into the CC systems in their cars.)
I'm not saying the switch should be left off unless the CC is actively being used, just wanted to help everyone be aware of why the switch is even there.
