After having had a chat with Pete and Jon, I decided that i will keep the switches I have been using to date as i am limited due to finances and they are effective for the purpose. One concern that Pete raised about them was that the plastic surround gave it a cheap feel, and as this is something i wish to avoid. He suggested that i could place a filter over those plastic surrounds so that only the red plastic is the only part exposed. This reduces the depth of the switches out side of the over form.
So this is a prototyping how this could work on the product:-
