Does hold (v.) indicate a press when the subject is a button?

If I want my reader to press a button continuously for five seconds, then release the button, can I write “Hold the button for five seconds”; or, must I be more explicit and write “Press and hold the button for five seconds”.

My argument for “hold the button for five seconds” is that in the context that I am using the term. It would be impossible for the reader to carry the button in their hand, it would also be reasonable to assume that the reader would not need to detain or embrace the button.

If you read “hold the button for five seconds” are you pressing the button or are you hovering your hand over the button?
