Industrial Snap-Action Switch

The Square D snap-action switch is a plunger-style limit switch rated for 15 A at 600 V AC and 0.5 A at 125 V DC. It provides one normally-open and one normally-closed contact for control circuits. The compact body measures 2.5 in wide, 1.1 in deep and 0.83 in high. Screw terminals accept standard ring or fork lugs for secure wiring.

Panel Mounting and Wiring

Mounting holes are spaced on 2.10 in centres, allowing direct attachment to panels, brackets or machine frames. The screw connections free up DIN-rail space because no separate terminal block is required. The plunger actuator suits applications where a cam, lever or moving part depresses the button. No auxiliary enclosures or special tools are needed for installation.

Sustained Load Behaviour

The snap-action mechanism maintains consistent contact force through repeated cycles, reducing bounce during long production runs. Silver-alloy contacts resist welding at the full 15 A AC rating, so temperature rise stays stable over extended shifts. The switch is not suited for loads exceeding the stated DC rating or for high-speed electronic signalling.

Questions about this item

How long before the 15 A @ 600 V AC contacts wear out under continuous cycling?

The snap-action mechanism is rated for 15 A at 600 V AC; actual contact life depends on load type, switching frequency and environmental conditions.

Does the switch generate noticeable heat or noise when conducting 15 A all day?

At its rated 15 A / 600 V AC the device operates silently; temperature rise stays within industrial limits for the screw-terminal housing.

What wiring and mounting hardware must I already have to install this plunger switch?

You need ring or fork terminals for the screw connections and a panel cut-out drilled on 2.10 in centres to match the mounting holes.
