|NKK Switches offers the SK series of miniature, antistatic, snap-in keylock switches. This series offers secure mounting and is ideal for designs requiring space-saving, minimum-security switching.
The SK series housing and bushing are made of high-insulating, glass fiber reinforced polyester capable of withstanding 15 kilovolts of electrostatic discharge, thus providing superior antistatic protection.
In addition, these devices are offered with solder lug and .071 inches (1.8 mm) quick connect for simple installation. Wire harness customization options are also available upon request, further simplifying set up. A behind panel dimension of .089 inches (22.7 mm) makes the SK model a perfect solution for applications where high-density mounting and a short behind-panel depth are required. Panel cutout dimensions are a mere .039 inch to .079 inch (1.0 mm to 2.0 mm).
The SK series has a crisp and positive detent mechanism that ensures accurate switch settings. In addition, the SK keylock has a high dielectric strength of 500 volts between contacts and case. The mechanical life of the SK series is rated at 30,000 operations minimum, while electrical life is at 10,000 operations minimum.
