NKK Switches Process Sealed Subminiature Toggle A11JB1-JA

The A Series is a family of sealed subminiature toggle switches designed for low-voltage, logic-level circuits. The switches feature a totally sealed body with epoxy-sealed or ultrasonically welded terminals to prevent contamination, and a patented STC contact mechanism for reliable operation. Terminals have a 0.100" x 0.100" (2.54mm x 2.54mm) spacing conforming to standard PCB grid layouts. Electrical ratings include a maximum resistive load of 0.4VA at 28V AC/DC, contact resistance of 50 milliohms maximum, and insulation resistance of 500 megohms minimum. The switches operate from -30°C to +85°C and withstand 50G shock and 10-55Hz vibration. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, with an electrical life of 50,000 operations. The toggle through-hole design includes a 26° throw angle and nonshorting contact timing. The case and toggle are made from glass fiber reinforced polyamide; contacts are phosphor bronze and brass with gold plating.
