NKK Switches Process Sealed Subminiature Pushbutton AB15CH

The AB15CH is a subminiature, sealed, PCB-mount pushbutton switch designed for low-voltage logic-level applications, with a 0.4VA maximum resistive load rating. It features a nonshorting contact mechanism, 50 milliohms maximum contact resistance, and 500 megohms minimum insulation resistance. The switch has a nominal operating force of 2.55N, a travel of 1.1mm, and is rated for 50,000 mechanical and electrical operations. The case is constructed of glass fiber reinforced polyamide with a polyacetal plunger and gold-plated phosphor bronze contacts. It operates from -30°C to +85°C and meets vibration and shock standards of 10-55Hz at 1.5mm and 50G respectively. Terminal spacing is 2.54mm x 2.54mm, conforming to standard PCB grids. The AB15CH variant has a right angle with bracket and a .295" (7.5mm) diameter white cap, as indicated by its ordering code.
