RS2101XC6 from Jiangsu RUNIC Tech, in a SC-70-6. 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	IN	input	Digital control input. TTL/CMOS-compatible logic pin selecting the switch position: logic 0 = NO OFF / NC ON, logic 1 = NO ON / NC OFF. VINH ≥ 1.5 V @ V+=5 V (1 V @ 3.3 V); VINL ≤ 0.6 V @ V+=5 V (0.5 V @ 3.3 V). Input leakage 1 μA max.
2	V+	power_in	Positive power supply, 1.8 V to 5.5 V. Absolute maximum 6.0 V referenced to GND. Quiescent supply current 1 μA max at V+=5.5 V.
3	GND	power_in	Ground (0 V) reference for the supply and control input.
4	NC	bidirectional	Normally-Closed analog switch terminal. Connected to COM when IN = 0. Analog signal range 0 V to V+. RON ≈ 2.4 Ω typ @ V+=5 V; continuous current ±300 mA (peak ±500 mA). May act as switch input or output.
5	COM	bidirectional	Common analog switch terminal (SPDT pole). Routes to NO when IN=1 and to NC when IN=0. Analog signal range 0 V to V+; ±300 mA continuous.
6	NO	bidirectional	Normally-Open analog switch terminal. Connected to COM when IN = 1. Analog signal range 0 V to V+. RON ≈ 2.4 Ω typ @ V+=5 V; continuous current ±300 mA (peak ±500 mA). May act as switch input or output.
