TS5A3157DBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NO	bidirectional	Normally open switch port. Bidirectional analog/digital signal path connected to COM when IN is High. Signal range 0 to V+.
2	GND	power_in	Ground reference for the device. Continuous current through GND rated ±100 mA (absolute max).
3	NC	bidirectional	Normally closed switch port. Bidirectional analog/digital signal path connected to COM when IN is Low. Signal range 0 to V+. Despite the pin name 'NC', this is NOT a no-connect; it is the Normally-Closed switch terminal.
4	COM	bidirectional	Common switch port. Bidirectional analog/digital signal path routed to either NO or NC depending on IN. Signal range 0 to V+.
5	V+	power_in	Positive supply input. Operating range 1.65 V to 5.5 V (single supply). Continuous current through V+ rated ±100 mA (absolute max).
6	IN	input	Digital switch select input. High = COM connected to NO; Low = COM connected to NC. Input is 5V tolerant regardless of V+ (0 to 5.5 V range).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ts5a3157dbvr.step`	97 KB	You want the bare part, or you mark your own boards.
`ts5a3157dbvr-etched.step`	2.2 MB	You want the part with `TS5A3157DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 540 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
