What it is and what it does
The XCMD2124M12 is a heavy-duty miniature limit switch rated for 240 VAC 1.5 A and 250 VDC 0.1 A, with a 1NO-1NC snap-action contact block. It is built for severe-duty environments requiring NEMA 1/2/4/4X/6/12/13 enclosures.
What the ratings mean for fit
The contact rating—240 VAC at 1.5 A—limits this switch to control-circuit loads; it's not a motor-rated power switch. The 250 VDC 0.1 A rating covers the low-energy side of a DC sensor bus or PLC input. For higher inrush or inductive loads, you'd step up to an XCMD in the same family with a higher ampacity (though the connector and mounting stay the same). The ZAMAK zinc-alloy body holds up to corrosion and impact, and the -13 to 158°F range covers both cold-storage and washdown heat cycles.
