Dayton SPDT Top Plunger Limit Switch 10A 300V IP65

SKU CH-Y4NS-8Z3J8

Compact SPDT limit switch with top plunger actuator, rated 10 A at 300 V and sealed to IP65

  • Product typeLight Switch
  • SPDT switching controls two circuits with one actuator
  • 10 A at 300 V AC or DC handles heavy loads

  • Miniature body fits tight spaces at 2.41 x 1.12 x 1.01 in
  • Screw terminals give secure, tool-friendly wiring

Compact SPDT limit switch for position sensing

The Dayton SPDT top-plunger limit switch provides reliable position detection in a miniature body measuring 2.41 in high, 1.12 in wide and 1.01 in deep. Its IP65 rating and screw-terminal connections suit surface-mount installations where dust and water jets are present. The switch carries a 10 A rating at 300 V for both AC and DC circuits.

10 A capacity with IP65 environmental headroom

Rated at 10 A and 300 V, the contacts handle typical control-circuit loads while the IP65 seal protects the mechanism from ingress in harsh environments. The single-pole double-throw action gives one normally-open and one normally-closed path for simple logic or safety interlocks. The vertical top-plunger actuator requires direct axial travel to operate, so side-loading or over-travel beyond the plunger stroke will cause premature wear.

Replaces worn miniature limit switches in existing

This unit serves as a direct drop-in replacement for failed miniature SPDT limit switches with the same mounting footprint and screw-terminal wiring. The upgrade is worthwhile when the original switch lacks an IP65 seal or when the actuator boot has deteriorated, allowing contaminants to enter. It is not suited for applications needing a roller lever, side plunger or maintained-contact action.

Questions about this item

Can the 10 A 300 V SPDT contacts switch the same control-circuit voltage as my existing relay?

The switch is rated for 10 A at 300 V AC or DC, so it will handle typical low-voltage control circuits that fall within those limits.

How do I verify the IP65 seal is intact after mounting the switch?

Inspect the plunger boot and housing for damage, then confirm the switch actuates cleanly at the 2.41 in body height without moisture ingress during a wet test.

Does the box include mounting hardware or only the switch body with screw terminals?

The switch ships with the miniature body, top plunger actuator and screw terminals; mounting screws for the surface-mount holes are not included.
