SK Keylock Switches

NKK Switches' SK series is ideal for designs requiring cost effective, space-saving, and minimum to medium security switching. This series features a 12 mm diameter bushing for standard panel openings and a behind panel dimension of 27.0 mm.Compact dimensions make the SK Series a perfect solution for applications where high density mounting and a short behind-panel-depth are required.

The SK Series’ crisp and positive detent mechanism ensures accurate switch settings. In addition, the SK keylocks have a high dielectric strength of 1,500 V between contacts and case. The mechanical life of the SK Series is rated at 30,000 operations minimum, and the electrical life is rated at 10,000 operations minimum. Switches in this series feature dust resistant interior construction to protect the contacts. Terminals are solder lug and epoxy sealed to prevent the entry of flux and other contaminants.
