Marquardt GmbH Pb Sw, Spst-No, 2A, 250Vac, Solder; Switch Operation Marquardt 01846.0201-01

The Marquardt 48AC8672 is a single-pole, normally open (SPST-NO) pushbutton switch designed for applications requiring a compact and reliable switching solution. It can handle a maximum contact current of 2A at 250V AC. The switch features solder lug terminals for secure connections and is built to endure up to 500,000 mechanical switching cycles, ensuring long-term reliability. This switch is rated for an operating force of approximately 1 N, with a maximum of 4 N for specific models. It has a low contact resistance of less than 100 mOhm under new conditions and an insulation resistance greater than 100 MOhm at 500V DC. The product is designed with a protection rating of IP 40, making it suitable for environments where dust and water exposure is a concern. The ambient temperature range for the switch is from -20 °C to +85 °C on the terminal side and -20 °C to +55 °C on the actuating side. The materials used include a PA housing and silver-plated terminals, contributing to its durability and performance. The switch complies with UL 94 V-2 flammability standards and has a glow wire test temperature of 850 °C, making it suitable for various applications in protection class II appliances.
