The document introduces the RoHS Directive 2002/95/EC and its annex, as well as the electrical, mechanical, and environmental characteristics of the 7813 SMD 3mm square sealed rotary switch. The switch is of SPDT type with a maximum current rating of 0.1mA and a maximum voltage of 16V. It also has good insulation resistance and heat resistance, and can operate in a temperature range of -55°C to +125°C. The switch has also undergone tests for shock, vibration, thermal shock, and soldering heat, and has a reliable rotational life. The switch is manufactured by 3M Co.
This datasheet describes the Bourns 7813 surface‑mount rotary switch, a 3 mm square sealed SPDT device. It lists the electrical characteristics such as contact rating, voltage, resistance, and insulation requirements, as well as mechanical dimensions and adjustment torque.
The document also covers environmental limits (temperature, shock, vibration), rotational life options (50 or 2000 cycles), and packaging information including tape‑and‑reel formats and recommended soldering profile.
