On/Off switch to replace dummy in centre dash?

[dvhttn]

Just bough a fast wireless charger phone holder for the motor (PD130 Estate) but want to add an on/off switch for it (don't want to constantly charge as it's an S7 so non-replaceable battery so want to take care of it ...). Can you get any that fit what are now blank panels by the radio? That is, above/below where the ESP and rear screen heater buttons are. I have 3 or 4 blank so it's an ideal place to have it (I can do any wiring behind the dash so that's not an issue).

Cheers.
