# Through-hole rotary coded DIP switch

A 10-position rotary coded DIP switch for through-hole mounting, set from the top: Nidec's SH-7000 series SH-7010C (real code, BCD) and SH-7030C (complementary code). It has a dark housing, a stainless steel cover, a light rotor with a setting slot, and six pins in two rows. The body is centred on the origin, with its underside on the board's top face (the XY plane). The pins lie along X, 2.54 apart, and the two rows are across Y.

`kind` is the type. The two types are the same size. `position` is the setting the slot points at, 0 to 9 (36 degrees a step).

- The body is 7.3 along the rows and 7.1 across them, and 3.7 high.
- The setting slot is 0.7 wide, 2.8 long and 1 deep.
- The pins are 0.6 wide and 0.15 thick, 2.54 apart. The rows are 7.62 apart, and the pins reach 3.5 below the board.
- PCB holes: six, Ø1, on a 2.54 grid.

- Page 2, Part Number Designation and Standard Specifications: C is through-hole pins, 10 positions, real or complementary code; net weight approx. 0.38 g.
- Page 1, Internal Structure: marking cover, cover and spacer stainless steel (SUS 304); "O" ring silicone rubber; rotor and housing polyphenylene sulfide; contacts and terminal pins copper alloy, gold plated.

**Proportions, for looks only.** The drawing doesn't dimension the following. They are scaled from page 4's views:

- The cover, 0.2 thick.
- The rotor, Ø3.3 and 1.4 deep, flush with the cover, in an opening 0.15 wider all round.
- Where the pins leave the housing: a short tab 1.0 above the board, then straight down outside the housing's side.

Materials follow page 1: the housing and rotor polyphenylene sulfide, which isn't on the material list, so `pet` (the closest density) is used, dark for the housing and light for the rotor. The cover is stainless steel (`stainless-304`), and the pins copper alloy (`copper`), gold coloured. **Mass check:** as modelled, 0.24 g housing + 0.07 g cover + 0.01 g rotor + 0.02 g pins = 0.34 g, against the sheet's approx. 0.38 g.

## Catalogue models

The old `Nidec Copal SH-7010 C` model names this part, so it maps to SH-7010C. It was measured on the reference model (2026-11-06) and agrees with the drawing:

| | Old model | Nidec drawing |
|---|---|---|
| Body | 7.3 x 7.1, 3.7 high | 7.3 x 7.1, 3.7 high |
| Pins | 0.6 x 0.16, 2.54 apart, rows 7.62 apart (centres), 3.5 below the board | 0.6 x 0.15, 2.54 apart, rows 7.62 apart, 3.5 below |

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