SPDT Rotary Lever Mini Limit Switch

This Dayton SPDT rotary lever mini limit switch provides single-pole double-throw switching in a miniature body rated for NEMA 12, 13, 4, 6 and 6P environments. It suits machine builders and maintenance technicians who need a compact side-actuated limit device for position sensing on conveyors, guards or automated equipment. The switch handles both AC and DC circuits at 10 A and 300 V. California Proposition 65 warnings apply for cancer and reproductive harm.

Contact ratings and environmental sealing

Rated at 10 A @ 300 V for both AC and DC loads, the switch carries the same current capacity across control and power circuits. The NEMA 12, 13, 4, 6 and 6P ratings confirm protection against dust, splashing water, hose-directed water and temporary submersion. No boot-sealed actuator is fitted, so the rotary lever operates directly in the sealed housing. Body dimensions are 1.97 in high, 1.57 in wide and .63 in deep for surface mounting.

Mounting and actuator configuration

Surface mounting holes accept standard fasteners for quick installation on panels or frames. The side-mounted rotary lever actuator delivers mechanical actuation from the side of the unit, simplifying linkage design in tight spaces. No additional accessories, wiring harnesses or configuration software are supplied with the switch. The bare switch body is the only item provided.

Questions about this item

How do I mount the Dayton SPDT rotary lever mini limit switch on a surface, and what step do installers often miss?

Use the two mounting holes on the 1.57 in wide by 1.97 in high body to secure it to a flat surface. The step often missed is aligning the side-mounted rotary lever so its travel clears the 0.63 in deep housing without binding.

What maintenance will the switch need over time, given its NEMA 12, 13, 4, 6 and 6P ratings?

The sealed NEMA ratings protect the SPDT contacts from dust, oil and water ingress, so no routine internal cleaning is required. Inspect the rotary lever and roller for wear or debris that could prevent full actuation, and verify the 10 A at 300 V contacts remain tight.

What is the first limit that appears under sustained use at the rated 10 A and 300 V?

The contact rating of 10 A at 300 V AC or DC is the primary electrical limit; sustained operation at that load will cause contact erosion before the miniature body or NEMA-sealed actuator reaches a mechanical or thermal limit.
