  • Screw terminals on 2.10 in centres simplify wiring

Industrial snap-action switch for 10 A AC circuits

The Square D snap-action switch provides a 10 A rating at 600 V AC and 1 A at 125 V DC. Its 2NO/2NC contact form suits control panels that need both normally-open and normally-closed circuits. A roller lever with 1.65 in actuator length converts linear motion into reliable switching. Screw terminals and 2.10 in mounting centres simplify panel installation.

Sustained-load behaviour in control panels

The snap-action mechanism delivers consistent contact force over repeated cycles, reducing contact bounce during continuous operation. Rated for 10 A at 600 V AC, it maintains stable performance in motor-control and lighting circuits without derating. The 2NO/2NC configuration allows redundant safety interlocks to remain active during extended duty. Screw terminals resist loosening under vibration in industrial environments.

Thermal and electrical characteristics in normal use

The switch body measures 2.5 in wide, 0.83 in high and 1.03 in deep, fitting standard enclosures. Contacts are rated for 10 A at 600 V AC and 1 A at 125 V DC, defining the thermal limits for continuous operation. No auxiliary cooling is required when operated within these ratings. The roller lever reduces mechanical wear, contributing to long-term reliability.

Questions about this item

How much heat does the 10 A @ 600 V AC rating generate during continuous operation?

The switch is rated for 10 A at 600 V AC and 1 A at 125 V DC; normal contact resistance keeps temperature rise low in typical industrial use.

What wiring and mounting hardware must I already have to install this snap-action switch?

You need screw-terminal wiring and a mounting surface drilled on 2.10 in centres to match the switch footprint.

Will the 1.65 in roller lever clear the same cam profile as my older Square D limit switch?

The lever actuator measures 1.65 in long; if the existing cam engages at that radius the switch will operate correctly.
