NKK Switches Process Sealed Subminiature Toggle A28HH

The Series A process sealed subminiature toggle switches are designed for low-voltage, low-current logic-level applications, featuring a totally sealed body to prevent contamination and support automated soldering and cleaning. They offer PCB terminals with standard 0.100" x 0.100" (2.54mm x 2.54mm) spacing and include toggle options in antistatic glass fiber reinforced polyamide. The mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, and 50,000 for other circuits, with an electrical life of 50,000 operations. Operating temperature ranges from -30°C to +85°C, and contact resistance is 50 milliohms maximum. The switches use a nonshutting contact mechanism with a 26° angle of throw and are rated for 0.4VA maximum at 28V AC/DC. Terminals are soldered via wave soldering, and the case is molded from glass fiber reinforced polyamide with phosphor bronze contacts plated in gold.
