Right-angle tactile switch, 6 x 6 mm

A right-angle (vertical) 6 x 6 mm through-hole tactile switch (SPST-NO), C&K's PTS645V series. It is a 6 x 6 mm tactile switch lying on its back in a sheet-metal frame, so the actuator is parallel to the board. The switch has a black housing and a metal face with four holes. The frame has a top plate, two side walls with a window onto the housing, and a bent leg from each wall. Terminals 1 and 2 go straight down from the housing.

The origin is midway between terminals 1 and 2, on the board's top face (the XY plane). The actuator points along +Y, and the frame's legs are 2.55 behind the terminals.

kind is the actuator's length code from the order code. force is the actuation force, which sets the actuator's colour and the part number.

Kind	Parts (by force L / M / H / K)	Actuator	From the front leads
31	PTS645VL31-2 LFS, VM31, VH31, VK31	round, Ø3.5	3.15 ±0.1
39	PTS645VL39-2 LFS, VM39, VH39, VK39	round, Ø3.5	3.85 ±0.1
58	PTS645VL58-2 LFS, VM58, VH58, VK58	round, Ø3.5	5.85 ±0.1
83	PTS645VL83-2 LFS, VM83, VH83, VK83	round, Ø3.5	8.35 ±0.1
J61	PTS645VJL61-2 LFS, VJM61, VJH61, VJK61	square, 2.4 side, 1.8 long, on a neck 1.4 long	6.15

Force	Actuation force	Actuator colour
L	130 grams	black
M	160 grams	blue
H	200 grams	gray
K	260 grams	red

For every kind:

The frame is 7.5 wide. Its top is 6.2 above the face's lower edge, and that edge is 1.0 above the board (4.95 - 3.95).
The actuator's axis is 4.05 above the board, and the switch's face is 2.3 in front of the terminals (the square actuator's 6.15 less its 3.85 beyond the face).
Terminals 1 and 2 are 0.7 wide and 0.3 thick, 4.5 ±0.15 apart, and reach 4.3 below the face's lower edge (3.3 below the board).
The frame's legs are 1 wide, 2.55 ±0.1 behind the terminals. They are 7 apart at the tips and 8.5 over their bends, and reach 3.95 below the board.
The frame's back is 4.2 behind the terminals.
The PCB holes are Ø1 for the terminals (4.5 ±0.05 apart) and Ø1.3 for the legs (7 ±0.05 apart, 2.55 ±0.05 behind).
The face has four Ø0.9 holes, 4.3 apart.

How To Order (page B-98): the order code (termination V, actuator shape J, actuation force L/M/H/K, length 31, 39, 58, 61 or 83, insertion type 2), and the lengths 3,15, 3,85, 5,85, 6,15 (square actuator only) and 8,35. Terminals are silver plated.

S STRAIGHT (page B-99): the 6 x 6 switch itself, 6 square and 3.45 from its terminal side to its face, used here for the housing.
J SQUARE ACTUATOR, VERTICAL THT (page B-100): the square actuator (6.2 from the front leads, 3.85 beyond the face, a 2.4 square stem 1.8 long on a neck 1.4 long), and the four Ø0.9 face holes 4.3 apart. This is the same frame and switch.
ACTUATION FORCE and ACTUATOR HEIGHT (page B-102): the actuator colours, and "Switch length from front leads for V only": 31 3,15, 39 3,85, 58 5,85, 83 8,35, each H ±0.1.

The sheet gives no weight and names no materials.

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

The frame's sheet thickness, 0.2, and the switch's metal face thickness, 0.3.
The gap between the housing and the frame's side walls: the walls are at the frame's 7.5 width, the housing 6 wide.
The side walls' outline: the back edge sloping from 3.0 above the board up to the top plate 3.2 behind the terminals, the lower front edge slanting from 0.7 in front of the terminals on the board up to the face's lower edge. Each wall has a window from 1.0 behind to 2.0 in front of the terminals, 2.0 to 3.9 above the board.
Where the legs bend: straight down to 0.6 below the board, out to the 8.5 width by 1.6, in to the 7 pitch from 2.0 to 3.0, then straight to the tip.
The square actuator's neck, Ø1.6, as the square actuator drawn on page B-101.

Materials are for looks and a rough mass. The housing is black polyamide (pa6), the face and the frame sheet steel (steel-c10), the actuator polyamide in its colour, and the terminals copper alloy (copper), silver coloured. Mass check: the sheet states no weight. PTS645VL31 as modelled is 0.13 g housing + 0.05 g face + 0.01 g actuator + 0.19 g frame + 0.02 g terminals = 0.40 g, and PTS645VL83 is 0.46 g.

Catalogue models

The old SW Tactile SPST Angled PTS645Vx31 2LFS, x39, x58 and x83 models name these exact parts, so they map to kinds 31, 39, 58 and 83. They were measured on the reference models (2026-11-06). They are simplified models: they have the right footprint, but the frame, legs and actuator differ from the drawing, as below.

C&K, *PTS645 Series, 6 mm Tact Switches*, dated 6 february 18, catalogue pages B-98 to B-103, from the copy at pdf.icgoo.net (<https://pdf.icgoo.net/productinfo/allpdf/5305a3c5-e437-3b12-913a-2860127444d6.pdf>; C&K's own site refused the download):

- How To Order (page B-98): the order code (termination V, actuator shape J, actuation force L/M/H/K, length 31, 39, 58, 61 or 83, insertion type 2), and the lengths 3,15, 3,85, 5,85, 6,15 (square actuator only) and 8,35. Terminals are silver plated.

- J SQUARE ACTUATOR, VERTICAL THT (page B-100): the square actuator (6.2 from the front leads, 3.85 beyond the face, a 2.4 square stem 1.8 long on a neck 1.4 long), and the four Ø0.9 face holes 4.3 apart. This is the same frame and switch.
- ACTUATION FORCE and ACTUATOR HEIGHT (page B-102): the actuator colours, and "Switch length from front leads for V only": 31 3,15, 39 3,85, 58 5,85, 83 8,35, each H ±0.1.

The sheet gives no weight and names no materials.

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

- The frame's sheet thickness, 0.2, and the switch's metal face thickness, 0.3.
- The gap between the housing and the frame's side walls: the walls are at the frame's 7.5 width, the housing 6 wide.
- The side walls' outline: the back edge sloping from 3.0 above the board up to the top plate 3.2 behind the terminals, the lower front edge slanting from 0.7 in front of the terminals on the board up to the face's lower edge. Each wall has a window from 1.0 behind to 2.0 in front of the terminals, 2.0 to 3.9 above the board.
- Where the legs bend: straight down to 0.6 below the board, out to the 8.5 width by 1.6, in to the 7 pitch from 2.0 to 3.0, then straight to the tip.
- The square actuator's neck, Ø1.6, as the square actuator drawn on page B-101.

Materials are for looks and a rough mass. The housing is black polyamide (`pa6`), the face and the frame sheet steel (`steel-c10`), the actuator polyamide in its colour, and the terminals copper alloy (`copper`), silver coloured. **Mass check:** the sheet states no weight. PTS645VL31 as modelled is 0.13 g housing + 0.05 g face + 0.01 g actuator + 0.19 g frame + 0.02 g terminals = 0.40 g, and PTS645VL83 is 0.46 g.

## Catalogue models

The old `SW Tactile SPST Angled PTS645Vx31 2LFS`, `x39`, `x58` and `x83` models name these exact parts, so they map to kinds 31, 39, 58 and 83. They were measured on the reference models (2026-11-06). They are simplified models: they have the right footprint, but the frame, legs and actuator differ from the drawing, as below.

Right-angle (vertical) 6 x 6 mm through-hole tactile switch (SPST-NO), C&K PTS645V series, from C&K's PTS645 data sheet (6 february 18): a 6 x 6 mm switch lying on its back in a sheet-metal frame, the actuator parallel to the board. Round actuator 3.15, 3.85, 5.85 or 8.35 mm from the front leads (PTS645Vx31/39/58/83), or the square 2.4 mm actuator 6.15 mm out (PTS645VJx61). Leads 4.5 apart, frame legs 7 apart 2.55 behind. The actuation force sets the actuator colour and the part number. See the README.

Right-angle tactile switch, 6 x 6 mm

The origin is midway between terminals 1 and 2, on the board's top face (the XY plane). The actuator points along +Y, and the frame's legs are 2.55 behind the terminals.

kind is the actuator's length code from the order code. force is the actuation force, which sets the actuator's colour and the part number.
