Its ZAMAK zinc alloy body and NEMA 1/2/4/12, IP66 enclosure mean it survives hose-down cleaning and dust ingress on packaging, food processing, or material handling lines. Contact rating is 10 A at 240 VAC and 0.27 A at 250 VDC, SPDT configuration with spring-return snap action. That AC rating handles typical motor starter and relay coil loads; the DC rating is low enough that you need to verify the switched DC current stays under 270 mA — a common trip point for solenoid valves or DC brake coils in this class. The rotary head carries a variable-length steel roller lever with 90 degrees of total travel. Operating force is 33.3 oz-in, which gives a positive snap without requiring heavy mechanism contact — suitable for cam-actuated or linear-slide position detection where overtravel is limited. Approvals include UL and CSA, and the switch complies with EN/IEC 60204-1 (machinery safety) and EN/IEC 60947-5-1 (control circuit devices). That covers the documentation a panel builder needs for CE-marked machinery or UL 508A listed panels.","metaTitle":"Square D XCKJ10543H7 Limit Switch, SPDT, 10A 240VAC, NEMA 4X","metaDescription":"Square D XCKJ10543H7 heavy duty limit switch.
