The A Series is a family of sealed subminiature toggle switches designed for low-voltage, low-current logic-level circuits. All variants feature a totally sealed body, gold-plated phosphor bronze contacts, and a 26° toggle throw with nonshorting contact timing. They have a 0.4VA maximum resistive load capacity at 28V AC/DC, 50 milliohms maximum contact resistance, and 500 megohms minimum insulation resistance. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, with 50,000 operations for other circuits. The switches mount directly to PCBs with .100" (2.54mm) terminal spacing, and operate from -30°C to +85°C. Terminals are epoxy sealed or ultrasonically welded to prevent contamination. The A12HW variant is not explicitly listed, but the series includes vertical PC terminals and .394" (10.0mm) bat toggles with snap top caps, which describe this model's form and function.
