Low & Medium Security Keylocks Series SK Distinctive Characteristics 12mm diameter bushing for easy panel cutout preparation and high density mounting. Epoxy sealed terminals prevent entry of flux and other contaminants. Short behind panel dimension - only 1.063” (27.0mm). High dielectric strength of 1,500 volts between contacts and case. Detent mechanism gives crisp, positive action for accurate switch setting. Dust resistant interior construction protects contacts.
