The A Series is a family of process sealed subminiature toggle switches designed for low-voltage, low-current logic-level circuits. The switches feature a totally sealed housing, STC contact mechanism for reliable actuation, and .100" x .100" (2.54mm x 2.54mm) terminal spacing compliant with standard PCB grid patterns. Contact resistance is 50 milliohms maximum, insulation resistance is 500 megohms minimum at 500V DC, and dielectric strength is 500V AC between contacts and case. Electrical life is 50,000 operations minimum. Operating temperature ranges from -30°C to +85°C. Housing and toggle are made from glass fiber reinforced polyamide, with phosphor bronze contacts plated in gold. Snap-top toggle caps and vertical or right-angle PCB terminals are available options.
