This document describes the features and characteristics of the D2MC series and D2MC-01 series of rotary action basic switches. These switches have high reliability, light operating torque (0.5mN·m), and long mechanical life (over 10 million cycles). They are suitable for use in the field of small loads and feature gold alloy contacts with a horizontal bar construction and disc spring. The document also provides specifications and ratings for different models.
The D2MC basic switch is a lightweight‑torque, high‑reliability rotary switch designed for low‑load applications. It features a 0.5 mN actuation torque, a mechanical life exceeding 10 million cycles, and a robust alloy contact system.
The manual details rated voltage and current (AC 125 V, 5 A), environmental limits (20 °C ± 2 °C, 65 % ± 5 % RH), safety certifications (UL, CSA C22.2 No.55), and step‑by‑step drive‑rod installation. The drive rod is sold separately and must be inserted into the shaft hole as illustrated. This manual is written in Chinese.
