NKK Switches Process Sealed Ultra-Miniature Toggle G18AH

The G18AH is a member of the G Series, a sealed ultra-miniature toggle switch designed for low-voltage, low-current logic-level circuits. It features a DPDT (on-off-on) circuit with right-angle PCB terminals and a .150" (3.8mm) column toggle actuator. The switch has a total height of 0.276" (7.0mm), a terminal spacing of 0.100" (2.54mm), and weighs 0.25 gram. Construction includes glass fiber reinforced polyamide for the case, actuator, and base, with phosphor bronze contacts gold-plated for reliable performance. Electrical ratings include a maximum resistive load of 0.4VA at 28V AC/DC, contact resistance of 80 milliohms maximum, and insulation resistance of 500 megohms minimum. The switch operates within a temperature range of -25°C to +85°C, withstands 50G shock, and has a mechanical and electrical life of 50,000 operations. The STC contact mechanism provides positive detent actuation and enhanced logic-level reliability.
