NKK Switches Process Sealed Subminiature Pushbutton AB15BW

The AB15BW is a subminiature, sealed, pushbutton switch designed for logic-level applications, with a subminiature footprint saving PCB space. It features a totally sealed body to prevent contamination and supports automated soldering and cleaning. The switch has a nonshorting contact mechanism with pretravel of 0.7mm and overtravel of 0.4mm, a nominal operating force of 2.55N, and a maximum contact resistance of 50 milliohms. It operates between -30°C and +85°C and meets vibration and shock specifications of 10-55Hz at 1.5mm peak-to-peak and 50G acceleration. The terminals have 2.54mm spacing conforming to standard PCB grids and are soldered via wave or manual methods. The STC contact mechanism provides positive detent actuation and enhanced reliability. The AB series has no UL or CSA certification and is intended for low-voltage, low-current circuits.
