NKK Switches Process Sealed Keylock SK12BG30

The SK series is a sealed keylock switch designed for low-voltage, low-current logic-level circuits. It features a sealed body with a disposable boot, molded-in terminals, and a bifurcated self-wiping contact mechanism for reliable operation. The switch has a 90° angle of throw for two-position models and 45° for three-position models, with contact timing that is break-before-make. It mounts via PCB terminals with 0.100-inch (2.54 mm) spacing, available in straight or right-angle configurations. Electrical capacity is 0.4 VA maximum at 28 V AC/DC, with contact resistance under 80 milliohms and insulation resistance over 100 megohms. Mechanical life is rated at 30,000 cycles, electrical life at 10,000 cycles. Operating temperature ranges from -25°C to +70°C. The switch is constructed with a brass key, polyacetal tumbler barrel, zinc alloy bushing, and beryllium copper contacts with gold plating. No UL or CSA certifications are listed.
