ML1S Series temperature switches are economic, bi-metallic, factory pre-set temperature switches that complement both our new and traditional temperature switch lines. The ML1S features a one-piece, brass thermowell design, which houses a bi-metallic, SPST snap switch. This one piece, brass housing comes standard with 1/2" process and conduit connections is rated NEMA 4 and IP65 and is UL and CSA recognized. Switching action is SPST, wired normally open or closed and rated for 15 amps @ 125 VAC, 10 amps @ 250 VAC. The one-piece design offers integrity against leaks vs. other welded two-piece designs. For low or high limit alarm, shut-off, or control, the ML1S is ideal for OEM applications when a compact, inexpensive temperature switch is required.
