Short behind panel dimension - only.06 (7.0mm). High dielectric strength of,500 volts between contacts and case.

2 Series SK Distinctive Characteristics mm 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.06 (7.0mm). High dielectric strength of,500 volts between contacts and case. Detent mechanism gives crisp, positive action for accurate switch setting. Dust resistant interior construction protects contacts. Actual Size 0
