描述

The HA1R-2C2-B is a round selector pushbutton switch from IDEC's H6 Series designed for 90° 2-position operation with maintained contact action. It features gold contacts in a DPDT (double-pole double-throw) configuration, providing independent left and right contact sets with NO (normally open) and NC (normally closed) terminals on each side. The switch operates across a temperature range of -25°C to +55°C (no freezing) with storage capability from -30°C to +80°C, and maintains contact resistance of 50 mO maximum with insulation resistance of 100 MO minimum (500V DC megger). It is rated for IP65 protection (IEC 60529) and withstands vibration of 5 to 55 Hz at 0.5 mm amplitude and shock resistance of 100 m/s² (10G) during operation. The switch is ideal for heavy-duty machine tool applications and industrial control panels where reliable, sealed operation and ease of operator access are required.
