Miniature Limit Switch with Roller Plunger

This Dayton SPDT limit switch uses a vertical roller plunger actuator for precise position sensing in industrial equipment. The miniature body measures 1.97 in high by 1.57 in wide by 0.63 in deep and carries NEMA 4, 6, 6P, 12 and 13 ratings for dust and water ingress protection. It is suited to automation engineers and maintenance technicians who need a compact, sealed switch for conveyor stops, machine guards or door interlocks.

Replaces worn snap-action switches on existing

The switch handles 10 A at 300 V AC or DC, matching many legacy miniature limit switches so it can serve as a direct drop-in replacement. The jump is worth it when the old actuator has lost repeatability or the housing seals have failed, because the roller plunger reduces side-load wear and the NEMA-rated enclosure restores environmental protection. Buyers who need a different actuator style, such as a plain plunger or lever, cannot use this model.

Verify mounting pattern and voltage before ordering

Confirm that the surface-mount hole spacing on your machine matches the switch footprint and that the control circuit does not exceed 300 V AC or DC. The actuator operates from the top only, so ensure the target cam or dog approaches perpendicular to the roller axis. No boot seal is fitted, so the switch relies on its NEMA-rated body for ingress protection.

Questions about this item

What are the body dimensions for mounting this miniature limit switch?

The switch body measures 1.97 in height, 1.57 in width and 0.63 in depth for surface mounting.

How do you wire the SPDT contacts on this vertical roller plunger switch?

Connect the common, normally open and normally closed terminals to the load circuit; the SPDT form switches between the two throw positions when the roller plunger is actuated.

What environmental protection do the NEMA 12, 13, 4, 6 and 6P ratings provide for this switch?

These ratings indicate protection against dust, dirt, oil, water ingress and temporary submersion, suitable for harsh industrial environments.
