NKK Switches Process Sealed Subminiature Toggle A18EV1

The A Series is a family of sealed subminiature toggle switches designed for low-voltage, low-current logic-level applications. The switches feature a totally sealed body to prevent contamination and support automated soldering and cleaning. Terminals have a 0.100" x 0.100" (2.54mm x 2.54mm) spacing conforming to standard PCB grid patterns. The contact mechanism provides nonshorting, break-before-make operation with a 26° throw angle. Electrical capacity is 0.4VA maximum at 28V AC/DC, with contact resistance of 50 milliohms max and insulation resistance of 500 megohms min. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, and 50,000 for others. Electrical life is rated at 50,000 operations. Operating temperature ranges from -30°C to +85°C. The case and toggle are made of glass fiber reinforced polyamide; contacts use phosphor bronze with gold plating. The A Series has not been certified by UL or CSA.
