NKK Switches Process Sealed Subminiature Antistatic Pushbutton BB25AP

The BB25AP is a subminiature, sealed, antistatic pushbutton switch designed for logic-level applications, featuring a double-pole, momentary, or alternate action circuit with right-angle PCB terminals. It has a 6mm diameter bushing, .100" x .100" terminal spacing, and operates within a temperature range of -30°C to +85°C. The switch provides a nominal operating force of 2.55N (momentary) or 2.94N (alternate action), with a mechanical and electrical life of 50,000 operations for momentary and 25,000 for alternate action. Contact resistance is 50 milliohms maximum, and insulation resistance is 500 megohms minimum at 500V DC. The case is constructed from glass fiber reinforced polyamide with a carbon-blended polyamide bushing for static dissipation. It meets UL94V-0 flammability standards. Total travel is 1.1mm for momentary and 2.0mm for alternate action. Its dimensions conform to standard PCB grids and include a .201" diameter plunger cap.
