Compact limit switch for automated equipment

The Square D 9007MS10S0300 is a miniature plunger-type limit switch rated for 10A at 300V AC and 5A at 300V DC. Its SPDT contact form suits control circuits that need a single-pole changeover action. The boot-sealed actuator and NEMA 1, 2, 4, 6, 6P, 12, 13 ratings allow installation in indoor and wash-down environments.

Electrical and mechanical limits of the plunger

The switch breaks 10A resistive at 300V AC or 5A at 300V DC; inductive or lamp loads will reduce usable current. Actuator travel is .67 in and the body measures 1.75 in high, 1.58 in wide and .62 in deep. NEMA 6P rating confirms protection during prolonged submersion, but the device is not rated for hazardous-location use.

Verify mounting space

Confirm the .67 in actuator over-travel clears your machine guard or cam profile. Ensure the control voltage does not exceed 300V AC or DC and that the load type matches the SPDT contact rating. The miniature body fits tight enclosures, yet the 1.75 in height may conflict with shallow panels.

Questions about this item

Should I pick the 9007MS10S0300 or a different limit switch model?

The 9007MS10S0300 is a miniature plunger type rated 10A at 300V AC and 5A at 300V DC with SPDT contacts. Choose it when you need a compact, boot-sealed switch that fits a 1.75 in high by 1.58 in wide by 0.62 in deep body and carries NEMA 1, 2, 4, 6, 6P, 12, 13 ratings.

What does the 10A 300V AC rating mean once the switch is installed in a machine?

It means the contacts can safely interrupt a 10 ampere resistive load at up to 300 volts AC in normal operation. The same switch handles 5 amperes at 300 volts DC. Exceeding either value risks contact welding or premature failure.

Which wiring standard does the SPDT contact form follow and what does it limit in practice?

SPDT provides one common, one normally open and one normally closed terminal, allowing a single plunger action to switch between two circuits. The 300V AC/DC ceiling limits the maximum voltage you can apply across any contact pair.
