## Notes

- Omron's D2F is the common 12.8 × 5.8 × 6.5 mm miniature snap-action switch; SS is its 19.8 mm subminiature family; V is the 15 A general-purpose basic switch with #187 (4.8 mm) quick-connect terminals. These are the sizes people search when they replace a limit or door switch.
- D2F: body 12.8 (±0.15) × 5.8 (±0.15) × 6.5 (±0.1) mm and the two Ø2.0 (+0.12 / 0) mounting holes come from the leocom copy of the data sheet, whose own extraction warns that drawing labels are hard to read; the 'W × H × D' header (12.8 × 6.5 × 5.8) fixes the order. A mounting-hole spacing of 12.7 mm appeared in that read but was not confirmed as a hole-centre spacing, so it is not used. The OnlineComponents copy states 'use M2 screws together with washers' and terminals on a '2-pitch (2 × 2.54 mm)' spacing. General tolerance ±0.4 mm unless otherwise stated.
- SS-5GL / SS-01GL: body 19.8 × 6.4 × 10.2 and lever 14.5 mm are the spec header of TME's page. The data sheet outline shows hole callouts '3-1.6 dia.' and '2.35 dia.' plus 9.5 ± 0.1 and 2.5 ± 0.07, but the reader could not say which belongs to the mounting holes, so no mounting figure is given.
- V-15: two reads agree on the #187 quick-connect terminal (t = 0.5, tolerance +0.13 / −0.03 as printed) and on a Ø3.1 mounting hole; the V-15G sheet says the K models have Ø2.9. The numbers 22.2 ± 0.1, 27.8, 37.8 ± 0.8 and 10.3 ± 0.1 appear in the outline drawings, but their labels (hole spacing or body width) were lost in both extractions, so none is assigned here. Limit switches (D4MC, ME-8108) were not reached.
