Mini Limit Switch SPDT

The Dayton Mini Limit Switch is a compact SPDT limit switch with a vertical cross roller actuator designed for position sensing in industrial machinery. It suits maintenance engineers and OEM assemblers who need a small-footprint switch for automated equipment.

SPDT 10 A 300 V contacts

The single specification that decides fit is the contact rating: 10 A at 300 V for both AC and DC loads with an SPDT contact form. This rating determines whether the switch can handle the control circuit current in your application.

Surface mount NEMA 12 13 4 6 6P

The switch mounts on a flat surface using its 1.57 in by 1.97 in body with a 0.63 in depth and carries NEMA 12, 13, 4, 6 and 6P enclosure ratings. Misalignment of the cross roller actuator during installation is the most common cause of premature wear or missed actuation.

Questions about this item

What does the 10 A rating mean when this switch is installed in a real machine?

The switch can carry up to 10 A at 300 V on both AC and DC circuits, so it will handle typical control-panel loads without overheating.

How does the SPDT contact form limit what this switch can do in practice?

SPDT gives one common, one normally-open and one normally-closed contact, allowing a single actuator to toggle between two circuits or signal both states.

What mounting space does the 1.97 in high, 1.57 in wide, 0.63 in deep body need?

A flat surface with at least those dimensions plus clearance for the top-mounted cross-roller actuator to travel freely.
