LED buttons come in many sizes and shapes. you might try looking at the specs for a few on an electronic component supplier's (or retailer's) website.

OF is an acronym for Operating Force. The force needed to be applied to the Actuator to move from the free position to the operating position. The operating force is given in N or Nm.

As an example,

shows OF Max of 250 grams.
