This APEM Inc. 646NH/2 toggle switch is designed for robust applications requiring a Double Pole Double Throw (DPDT) configuration. It features a reliable On-On switch function, making it suitable for various control applications. The switch is rated to handle 10 Amperes at 250 Volts, ensuring performance in moderate to high current circuits.

Constructed for durability, the 646NH/2 has a panel mount design with a M12 x 0.75 bushing thread and requires a 12.20mm diameter cutout. The termination style utilizes 0.250" (6.3mm) quick connect terminals for easy and secure connections. Its operating temperature range is from -20°C to 55°C, and it features a flatted actuator.

The internal components are made from quality materials, including a polyester UL94-V0 case, brass nickel-plated actuator, brass nickel-plated or zinc die-cast bushing, and silver/nickel alloy contacts. The switch offers a peak current rating of 30A max. during 1/2 sine and an initial contact resistance of 10 mΩ max. It also boasts an insulation resistance of 1,000 MΩ min. at 500 VDC and a dielectric strength of 2,000 Vrms min. between terminals.
