Product Button Protrusion Height Tool

Record signed button protrusion above the enclosure face on one shared elevation axis; negative means recessed.

Description

Subtract enclosureFaceLevel from buttonTopLevel for protrusion.

A signed fit margin compares available space with an object and explicit allowances. Volume sufficiency, radial gaps, and diametral clearance are different conditions.

Subtract enclosureFaceLevel from buttonTopLevel for protrusion.

When to use this tool

Use Product Button Protrusion Height when you need one transparent product fit or travel-margin term.

How to use the tool and how it works

  1. Enter buttonTopLevel, enclosureFaceLevel. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read protrusion. Use the output convention below.

Limitations and assumptions

  • Levels must share datum and length unit; negative protrusion is retained and no actuation, accessibility, sealing, or tolerance requirement is assessed.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
  • Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.

Alternative or Complementary methods

Check complete three-dimensional geometry, tolerances, materials, and operating conditions before judging actual fit or safety.
