Industrial Switch for Machine Control

The Square D snap-action switch is built for industrial equipment that requires a reliable 15-amp AC or 2-amp DC control circuit. It suits maintenance engineers and panel builders wiring safety interlocks, limit stops or motor starters in factories and process plants.

1NO/1NC Contact Form with Roller Lever

The single-pole double-throw block provides one normally open and one normally closed contact, so a single actuation can both stop one circuit and start another. The roller lever reduces friction and wear on the actuator, making it suitable for high-cycle cam or conveyor applications.

Screw Terminals on 2.10 in Mounting Centers

Wiring uses screw connections that accept standard ring or fork terminals, and the body mounts on 2.10 inch centers for direct replacement of many legacy Square D units. The 1.65 inch lever travel requires correct cam alignment; insufficient over-travel is the most common cause of missed actuation.

Questions about this item

What does the 15 A @ 600 V AC rating mean once the switch is installed?

The switch can carry up to 15 amps on an AC circuit of up to 600 volts, suitable for industrial lighting or motor-control circuits within those limits.

How do the screw terminals and 2.10 in mounting centres affect wiring and panel fit?

Screw terminals accept ring or fork lugs for secure connections, and the 2.10 inch hole spacing matches standard NEMA mounting patterns for panel or enclosure installation.

Will the 1.65 in roller lever and 2.5 in body width fit inside my existing enclosure?

The lever extends 1.65 inches from the switch body, which is 2.5 inches wide, 1.03 inches deep and 0.83 inches high — check those clearances against your enclosure interior.
