Dayton Mini Limit Switch SPDT Plunger

The Dayton Mini Limit Switch is a compact SPDT plunger switch rated at 10A and 300V for both AC and DC circuits. It suits control panels, safety interlocks and position sensing in industrial machinery where a small footprint is required. The switch body measures 1.97 in high, 1.57 in wide and 0.63 in deep, with NEMA 12, 13, 4, 6 and 6P enclosure ratings. Surface mounting simplifies installation on flat surfaces.

Replaces larger limit switches

This miniature switch replaces bulkier limit switches when panel space is tight but the same 10A 300V rating is needed. The jump is worth it when an application demands NEMA 4, 6 or 6P ingress protection in a body under two inches high. It is not for circuits exceeding 300V or currents above 10A, nor for designs that require a lever or roller actuator instead of a plunger.

SPDT contact form and NEMA ratings

The SPDT contact form provides one normally open and one normally closed path, limiting control logic to a single changeover function. NEMA 12 and 13 ratings cover indoor dust and dripping liquids, while NEMA 4, 6 and 6P add protection against hose-directed water and temporary submersion. The switch lacks a boot-sealed actuator, so the plunger itself is the primary seal. California Proposition 65 warnings apply.

Questions about this item

What mounting surface and spacing does the 1.57 in wide by 1.97 in high miniature body need?

The switch mounts on a flat surface using its 1.57 in by 1.97 in footprint; drill two holes matching the base pattern and secure with screws so the plunger aligns with the target travel path.

How do I wire the SPDT contacts correctly, and what mistake should I avoid?

Connect the common terminal to the power source, then run the normally open and normally closed leads to their respective circuits; the common error is swapping the NO and NC wires, which reverses the switch action.

When should I plan to replace the switch given its NEMA 4, 6, 6P and 12, 13 ratings?

The sealed construction resists water, oil and dust, but the mechanical plunger and SPDT contacts will wear after repeated cycles; inspect actuator travel and contact resistance annually and replace if the action feels gritty or the circuit becomes intermittent.
