Dayton Mini Limit Switch SPDT Vertical Roller Plunger

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.
