Marine Switch for Bilge & Lighting

The Hubbell MR123LRSP is a marine-grade rocker switch designed for 12 V DC electrical systems on boats. It carries a 5 A rating and uses an SPDT On/Off/On configuration to control two separate circuits from one position. A built-in red neon light shows when the switch is active. The black body fits a standard 0.875 in by 1.500 in panel cut-out.

Suits DC Panels — Not AC Mains

This switch suits boat owners wiring bilge pumps, navigation lights or a two-speed fan where a single toggle must select between two loads. The quick-connect tabs accept 0.250 in terminals for fast installation. It is not rated for AC mains voltage, so household or shore-power circuits need a different device. The operating range of 32 to 100 degrees F covers typical marine environments.

SPDT On/Off/On at 5 A 12 V DC

The contact form is the deciding specification: a single-pole double-throw mechanism rated 5 A at 12 V DC with an On/Off/On action. If your circuit requires a maintained centre-off position to run two separate devices from one feed, this switch matches that need. Any other voltage, current or switching sequence will require a different part.

Questions about this item

How do I wire the .250 in quick-connect tabs on this SPDT switch?

Crimp female .250 in quick-disconnect terminals onto each wire, then push them onto the five tabs — centre tab is common, the two pairs either side are the On/Off/On throws.

Will the red neon light need replacement during the switch's life?

The neon lamp is sealed inside the rocker body and is not user-replaceable; if it fails the entire switch must be swapped.

At what temperature does the 5 A @ 12 V rating start to derate?

The published operating range tops out at 100 Degrees F; above that temperature the 5 A DC rating is no longer guaranteed.
