It's often best to seperate the switch block first (it's only 2 phillips screws from underneath it). You can then get the contact cleaner directly onto the slider and clean it more thoroughly. It's a good chance to clean up all the switches when you have taken the housing off the handlebar.

Good to hear you are sorted now. As you could tell, sticky switches is a common problem and can keep happening over time. Once I cleaned mine as you have I sprayed some silicon spray into them and that helped to keep them working for longer. I found WD40 and contact spray works but seemed to dry up quickly.

Okay, just how far apart do you split the switch housings?

just enough to get the spritz wand inside?

I sure don't want to hear springs flying away.

You wont get as far as the springs. The 2 halves of the switch housing come apart easily and nothing will fall out. Just make sure you line up the choke control properly when you put the 2 halves back together.
