The Square D Osiswitch XCKJ261H7 is a heavy-duty, non-plug-in limit switch with a top rod plunger actuator. It carries (2) SPDT contacts rated 240 VAC 10 A and 250 VDC 0.27 A, so it handles typical motor control and interlock circuits on the AC side, but the DC rating is low — 0.27 A at 250 VDC means it's for signal-level DC loads, not solenoid or brake switching. The ZAMAK zinc alloy body and NEMA 1/2/4/12, IP66 enclosure mean it withstands washdown and dust ingress, making it a fit for food-and-bev or machine-tool environments where a standard limit switch would fail.
Connection is via a 1/2-inch NPT cable gland, so it mates directly to standard rigid or flexible conduit without an adapter. The top rod plunger head is a positive-break design for safety circuits — the rod is depressed by a cam or machine slide, and the snap-action contacts transfer. Approvals: UL and CSA, so it's accepted in North American panels without a separate evaluation.
