NKK Switches Process Sealed Subminiature Toggle A18AW

The A Series is a family of sealed subminiature toggle switches designed for low-voltage, low-current logic-level circuits. The switches feature a totally sealed body to prevent contamination and support automated soldering and cleaning. They have a .100" x .100" (2.54mm x 2.54mm) terminal spacing conforming to standard PCB grid patterns. Contacts are rated for 0.4VA maximum at 28V AC/DC, with contact resistance of 50 milliohms maximum and insulation resistance of 500 megohms minimum. Electrical life is rated at 50,000 operations minimum. Operating temperature ranges from -30°C to +85°C. The toggle actuator has a 26° throw, and the mechanism provides nonshorting (break-before-make) contact timing. Terminal variants include straight, right angle, and vertical mounting options. The switches are constructed with glass fiber reinforced polyamide housing and phosphor bronze contacts with gold plating. They have not been tested for UL or CSA certification.
