Through-hole tactile switch, 6 x 6 mm

A 6 x 6 mm through-hole tactile switch (SPST-NO), Omron's B3F-1000 series. It has a black housing, a metal cover with four corner rivets, a round plunger (or a projected plunger with a square stem), and four bent snap-in terminals. Ground-terminal types have a fifth terminal. The body is centred on the origin, with its underside on the board's top face (the XY plane). Terminals 1 and 2 are at -X and 3 and 4 at +X. The ground terminal, terminal 5, is at -Y.

kind is the B3F drawing. force is the operating force, which sets the plunger's colour and the part number.

Type	Parts (by force 0.98 / 1.47 / 2.55 / 4.9 N)	Height	Plunger	Terminal pitch x row	Over the bends	Ground terminal

For every type:

The body is 6 ±0.2 x 6 ±0.2, and its top is 3.4 above the board.
The terminals are 0.7 wide and 0.3 thick, and they reach 3.5 below the board.
The terminal pitch is ±0.5 on the part (±0.1 for the PCB holes).
The ground terminal's hole is 4.1 ±0.1 from the centre line, and its tab is 1.5 wide.

Omron, Tactile Switch B3F, Cat. No. A070-E1-08, from Omron's own site, https://omronfs.omron.com/en_US/ecb/products/pdf/en-b3f.pdf:

List of Models (pages 1 and 2): the heights, the plunger colours by operating force, and the part numbers.
Ratings/Characteristics (page 3): the weight of the 6 x 6 mm models is approx. 0.25 g.
Dimensions (page 4): B3F-1000, B3F-1100, B3F-1110 and B3F-1060 series.
Dimensions (page 5): B3F-1070, B3F-1050 and B3F-1150 series.

The general tolerance is ±0.4 mm. The data sheet names no materials.

Proportions, for looks only. The drawings don't dimension the following:

The metal cover's thickness, 0.3.
The four corner rivets: Ø1.4, standing 0.2 above the cover.
The projected plunger's neck under its stem, Ø1.4.
Where the 9.5 mm plunger narrows to its Ø3 top: 6.5 above the board.
The terminals' bends. Each terminal leaves the housing's side 0.9 above the board, runs out to the 7.7 (or 9) overall width, goes down, steps in to the pitch, and goes on down to the tail.

Materials are for looks and a rough mass. The housing is black polyamide (pa6), the cover sheet steel (steel-c10), the plunger polyamide in its colour, and the terminals copper alloy (copper), silver coloured. Mass check: B3F-1000 as modelled is 0.131 g housing + 0.060 g cover + 0.016 g plunger + 0.042 g terminals = 0.25 g, against the sheet's approx. 0.25 g.

Catalogue models

The Omron models map to their drawings:

Old models	Type
`B3F-100x`, `B3F-102x`, `B3F-106x`, `B3F-107x`	1000, 1020, 1060, 1070
`B3F-110x`, `B3F-112x`, `B3F-1110`	1100, 1120, 1110

They were measured on the reference models (2026-11-06) for B3F-100x, 107x and 1110:

	Over the bends	Body	Height	Terminals
old B3F-100x	7.68	6.0 x 6.0	4.3	6.5 x 4.5, 3.5 below
Omron B3F-1000	7.7 ±0.5	6 x 6	4.3	6.5 x 4.5, 3.5 below
old B3F-107x	7.68	6.0 x 6.0	9.5, the plunger narrowing to Ø3.04	6.5 x 4.5
old B3F-1110	8.96, 7.25 deep with the ground tab	6.0 x 6.0	5.0	7.5 x 4.5, 3.56 below
Omron B3F-1110	9 ±0.5, 7.25 deep	6 x 6	5	7.5 x 4.5, 3.5 below

The generic SW PUSH 6mm, H4.3mm, H5mm and H9.5mm models name no maker. They map to the B3F of the same height, because their body is the same 6.0 x 6.0 housing (measured through 3.3 above the board), the terminals are on the same 6.5 x 4.5 grid, and they reach 3.5 below the board. Their differences are below. The terminal spread varies between makers of the same part, as post lengths do for headers.

	Over the bends	Above the body	Plunger
generic 6 mm models	7.18	four corner posts to 4.0	Ø3.5, straight to the top (H9.5 too)
Omron B3F	7.7 ±0.5	rivets	Ø3.5 (B3F-1070: Ø3 top)

These models are not mapped:

SW PUSH 6mm H7.3mm, "no table read yet": it is a round Ø3.5 plunger 7.3 high. B3F has a 7.0 flat plunger and a 7.3 projected plunger with a square stem, and neither is this part.
H8mm and H13mm, "no table read yet": B3F has no switch of those heights.
The family's other switches (DIP switches, slide and toggle switches, other makers' tactile switches) are other parts. See COVERAGE.md.

# Through-hole tactile switch, 6 x 6 mm

`kind` is the B3F drawing. `force` is the operating force, which sets the plunger's colour and the part number.

| `B3F-110x`, `B3F-112x`, `B3F-1110` | 1100, 1120, 1110 |

They were measured on the reference models (2026-11-06) for B3F-100x, 107x and 1110:

|---|---|---|---|---|

| old B3F-100x | 7.68 | 6.0 x 6.0 | 4.3 | 6.5 x 4.5, 3.5 below |

| Omron B3F-1000 | 7.7 ±0.5 | 6 x 6 | 4.3 | 6.5 x 4.5, 3.5 below |

| old B3F-107x | 7.68 | 6.0 x 6.0 | 9.5, the plunger narrowing to Ø3.04 | 6.5 x 4.5 |

The generic `SW PUSH 6mm`, `H4.3mm`, `H5mm` and `H9.5mm` models name no maker. They map to the B3F of the same height, because their body is the same 6.0 x 6.0 housing (measured through 3.3 above the board), the terminals are on the same 6.5 x 4.5 grid, and they reach 3.5 below the board. Their differences are below. The terminal spread varies between makers of the same part, as post lengths do for headers.

|---|---|---|---|

These models are not mapped:

- `SW PUSH 6mm H7.3mm`, "no table read yet": it is a round Ø3.5 plunger 7.3 high. B3F has a 7.0 flat plunger and a 7.3 projected plunger with a square stem, and neither is this part.

- `H8mm` and `H13mm`, "no table read yet": B3F has no switch of those heights.

- The family's other switches (DIP switches, slide and toggle switches, other makers' tactile switches) are other parts. See `COVERAGE.md`.

# Through-hole tactile switch, 6 x 6 mm

A 6 x 6 mm through-hole tactile switch (SPST-NO), Omron's B3F-1000 series. It has a black housing, a metal cover with four corner rivets, a round plunger (or a projected plunger with a square stem), and four bent snap-in terminals. Ground-terminal types have a fifth terminal. The body is centred on the origin, with its underside on the board's top face (the XY plane). Terminals 1 and 2 are at -X and 3 and 4 at +X. The ground terminal, terminal 5, is at -Y.

`kind` is the B3F drawing. `force` is the operating force, which sets the plunger's colour and the part number.

| Type | Parts (by force 0.98 / 1.47 / 2.55 / 4.9 N) | Height | Plunger | Terminal pitch x row | Over the bends | Ground terminal |
|---|---|---|---|---|---|---|

| 1110 | B3F-1110 | 5 ±0.2 | flat | 7.5 x 4.5 | 9 | yes |

For every type:

- The body is 6 ±0.2 x 6 ±0.2, and its top is 3.4 above the board.
- The terminals are 0.7 wide and 0.3 thick, and they reach 3.5 below the board.
- The terminal pitch is ±0.5 on the part (±0.1 for the PCB holes).
- The ground terminal's hole is 4.1 ±0.1 from the centre line, and its tab is 1.5 wide.

Omron, *Tactile Switch B3F*, Cat. No. A070-E1-08, from Omron's own site, <https://omronfs.omron.com/en_US/ecb/products/pdf/en-b3f.pdf>:

- List of Models (pages 1 and 2): the heights, the plunger colours by operating force, and the part numbers.
- Ratings/Characteristics (page 3): the weight of the 6 x 6 mm models is approx. 0.25 g.
- Dimensions (page 4): B3F-1000, B3F-1100, B3F-1110 and B3F-1060 series.
- Dimensions (page 5): B3F-1070, B3F-1050 and B3F-1150 series.

The general tolerance is ±0.4 mm. The data sheet names no materials.

**Proportions, for looks only.** The drawings don't dimension the following:

- The metal cover's thickness, 0.3.
- The four corner rivets: Ø1.4, standing 0.2 above the cover.
- The projected plunger's neck under its stem, Ø1.4.
- Where the 9.5 mm plunger narrows to its Ø3 top: 6.5 above the board.
- The terminals' bends. Each terminal leaves the housing's side 0.9 above the board, runs out to the 7.7 (or 9) overall width, goes down, steps in to the pitch, and goes on down to the tail.

Materials are for looks and a rough mass. The housing is black polyamide (`pa6`), the cover sheet steel (`steel-c10`), the plunger polyamide in its colour, and the terminals copper alloy (`copper`), silver coloured. **Mass check:** B3F-1000 as modelled is 0.131 g housing + 0.060 g cover + 0.016 g plunger + 0.042 g terminals = 0.25 g, against the sheet's approx. 0.25 g.

The generic `SW PUSH 6mm`, `H4.3mm`, `H5mm` and `H9.5mm` models name no maker.

Their differences are below. The terminal spread varies between makers of the same part, as post lengths do for headers.
