CT31021N020 is a sealed toggle switch designed for reliable switching applications requiring environmental protection and high electrical ratings. The switch features a completely sealed switching chamber with IP67 front panel sealing, ensuring protection against dust and moisture ingress. It is rated up to 10A at 250VAC and supports both single-pole and double-pole configurations with three terminal options (screw, solder, or quick-connect). The switch delivers 100,000 mechanical lifecycles with an operating temperature range of -40°C to +85°C, initial contact resistance of 10mO maximum at 1A 2VDC, and dielectric strength of 2.5kVrms between terminals. This combination of sealed design, high electrical ratings, and extended lifecycle makes it suitable for industrial control panels, marine equipment, and other applications requiring robust switching in harsh environments.
