The Square D / Telemecanique Osiswitch XCKJ10513 is a heavy-duty limit switch rated for 240 Vac at 10 A. It carries a 1NO-1NC contact configuration with spring-return snap action, so each actuation gives a clean make-break transition — no slow creep on the contacts. The rotary head accepts a lever arm (not included) for cam or slide actuation in the machine cycle. The body is die-cast Zamak (zinc-aluminum alloy), which resists corrosion and mechanical impact in industrial environments. Screw-clamp terminals accept stranded or solid wire without ferrules, making field replacement straightforward.
Approvals and sourcing posture
This part carries UL 508, CSA C22.2 No. 14, and CCC approvals, so it is accepted for panel builds in North America and China without additional agency review. The UL 508 listing covers industrial control equipment; CSA C22.2 No. 14 is the Canadian counterpart for industrial limit switches.
Installation and operating range
Operating temperature range is -13 to 158 °F (-25 to 70 °C), covering most indoor and sheltered outdoor installations. The snap-action mechanism is rated for a high mechanical life — typical for this class — but the exact cycle count is not listed here; the spring-return ensures the switch returns to its normal state when the actuator is released. Mounts via the standard limit-switch body pattern (30.5 mm fixing centres, M5 screws — verify with the actual lever arm you intend to use). The rotary head can be repositioned in 90° increments to suit the approach direction of the cam or flag.
