Control Actuation Forces: legend_switch
MIL-STD-1472F control actuation force and displacement requirements — min/max resistance (N) and displacement (mm or degrees) for every control type by hand condition (bare/gloved/heavy handwear/foot). Covers pushbuttons, foot switches, keyboards, toggle switches, legend switches, rocker switches, levers, isotonic joysticks, pedals, mouse buttons, and handwheels per Section 5.4 Figures 12-21 and Tables IX, X, XII.
| control type | record id | hand condition | notes | parameter | unit imperial | unit metric | value max imperial (lb, oz, or in (see unit_imperial)) | value max metric (N or mm or deg (see unit_metric)) | value min imperial (lb, oz, or in (see unit_imperial)) | value min metric (N or mm or deg (see unit_metric)) |
|---|---|---|---|---|---|---|---|---|---|---|
| legend_switch | legend_switch_membrane_conductive_displacement | bare_hand | Conductive membrane displacement | displacement | in | mm | 0.04 | 1 | 0.04 | 1 |
