The 2GK54-78 is a G-Series toggle switch designed for general-purpose industrial and commercial applications. It features a sealed bat actuator (78 designation) with screw terminal connections, rated for 10A at 250VAC or 15A at 125VAC, with 3/4 HP capability at 125-250VAC. The switch offers a dielectric strength of 1000V (UL/CSA) between live and dead metal parts, electrical life of 50,000 cycles under maintained load and 25,000 cycles for momentary operation, and mechanical life of 100,000 cycles. Operating temperature range spans 0°C to 85°C, with UL, CSA, and VDE approvals for select circuits. This switch is suitable for low voltage 12/24V DC applications and is commonly used in marine, food service, generator control, industrial control, and office automation environments.
