Dayton Compact Limit Switch SPDT Top Roller

Compact SPDT Limit Switch

The Dayton compact limit switch uses a top-mounted roller plunger to detect mechanical position in industrial and automation equipment. Its single-pole double-throw contacts switch both AC and DC circuits at 10 A and 300 V, making it suitable for control panels, safety interlocks and machine sequencing. The miniature body fits tight enclosures where full-size switches cannot be accommodated.

Electrical and Environmental Limits

The switch carries a NEMA 1 rating, so it is intended for indoor use where falling dirt is the primary concern. Contact ratings are fixed at 10 A @ 300 V for both AC and DC, and the SPDT form provides one normally-open and one normally-closed path without additional poles. No boot seal is fitted, so the actuator is not protected against moisture or heavy contamination.

Mechanical Build and Mounting

The body measures 2.41 in high, 1.12 in wide and 1.01 in deep, with a 1.51 in actuator length that positions the roller for cam or dog engagement. Surface mounting holes allow direct attachment to panels or brackets without a separate base. The roller plunger reduces friction and wear compared with a plain plunger, extending service life in repetitive actuation cycles.
