Sticky switches and buttons.

[Sr.]

I have one 2 way toggle switch that doesn't spring back like the others... sunny thing is, it's probably the one I've used the least.

 

Also the 2 position switch on the forward portion of the throttle (where the ring finger would sit) used to spring back, but now it tends to get hung, mostly forward presses.

 

Is some way to free these up or replace them?

You can try silicon grease.  Do not use WD40 or other petroleum based lubricants.
