Hella Marine 10A Delay-Off Timer Control 12V
Hella Marine 10A Delay-Off Timer Control 12V — Product description
The Hella Marine 10 amp delay-off timer control does one job and does it well. It powers a 12 volt accessory, then shuts it off automatically once the delay runs out. Five spade terminals make it a clean inline add to an existing switch. It's the kind of small, marine-built part you wire in once and forget about.
The Hella Marine 10 amp delay-off timer control is one of those small parts that quietly makes a boat's wiring smarter. Its job is simple. You give it 12 volt power and a trigger, it runs your accessory, and when the trigger drops it keeps that load alive for a set delay before shutting it off on its own. No relay to babysit, no switch you have to remember to flip back. That's the whole point of a delay-off timer, and this one does it without any fuss.
Where does that come in handy on the water? Plenty of places. Think courtesy and cockpit lights that you want on for a minute or two after you kill the main switch, so you're not stepping around the deck in the dark. Think a cabin fan or a small blower you'd rather let run on a bit after the engine's off. Anglers wire these in for accessory circuits that shouldn't be left on by accident. On a lot of 20 to 25 foot center consoles and runabouts, it drops in as an accessory timer alongside the switch panel that's already there, and it just works.
Wiring is straightforward thanks to the five spade terminals. You've got power, ground, a trigger, and the load, and everything pushes on without a soldering iron. A few things we tell every customer before they start. Fuse it. Put an inline fuse sized under the 10 amp rating so the timer and your wiring are both protected, and keep the actual load comfortably below that ceiling. Give it a clean ground straight back to the battery negative, especially on an aluminum hull, or you can chase phantom triggers all day. And hit those spade terminals with a little dielectric grease. Vibration is the enemy of any push-on connection on a boat, so a dab of grease and a zip tie on the harness go a long way toward a connection that stays put.
One thing worth checking before you wire it in for anything time-critical. This is a fixed-function delay-off control, not a dial-adjustable timer. The delay is what it is, so pull Hella's spec sheet and confirm the timing suits the job you have in mind. For most courtesy-light and accessory duties that's a non-issue, but if you need a specific, tunable shutoff window, it's better to know that up front.
This is Hella Marine, so the build is what you'd expect from a brand that's been making fit-and-forget electrical gear for boats for decades. The housing is compact enough to tuck behind the dash or inside a console where helm space is tight. One honest note on mounting. Like any current-carrying device, it'll warm up when it's working near the top of its range, so give it a little air and keep it out of a spot where it sits in standing bilge water. Dry, ventilated, and vibration-isolated is the recipe for a part that lasts.
So who's this for? Anyone who wants a set-and-forget auto-off on a modest 12 volt circuit without wiring up a full electronic timer module. It's ideal for lighting and light-duty accessory loads. It's not the part for a big bilge pump or anything that pulls real amperage, because the 10 amp rating is a hard ceiling and inrush from a motor can eat into that headroom fast. Match the timer to a sensible load and it'll do exactly what it says on the label. If you're not sure whether your circuit fits inside the rating, give us a call and we'll walk through it with you before you buy.
Bottom line, it's a simple, marine-built delay-off timer from a brand boaters trust. Wire it once, size it right, and you'll forget it's even there. Which is exactly what you want from a part like this.

Frequently asked questions
What does a delay-off timer actually do?
It keeps a 12 volt load powered for a set delay after its trigger drops, then shuts it off on its own. So a light or fan stays on for a little while after you flip the main switch, then cuts out automatically. No switch to remember.
What can I run on the 10 amp rating?
Light-duty 12 volt circuits like courtesy lights, cockpit lights, small fans, and accessory loads. Keep the actual draw comfortably under 10 amps and fuse it below the rating. It's not sized for a big bilge pump or a motor load, where inrush eats into the headroom fast.
How does it wire in with five spade terminals?
You've got power, ground, a trigger, and the load across the five push-on spade terminals, so no soldering is needed. Follow Hella's wiring diagram for the exact terminal assignments before you connect it.
Is it 12 volt only?
Yes. This is a 12 volt DC control. Don't wire it into a 24 volt system.
Where should I mount it?
Behind the dash or inside a console works well since it's compact. Keep it dry, give it a little air, and get it out of any spot that sees standing bilge water. Like any current-carrying part, it warms up near the top of its range, so ventilation helps it last.
Do I need to fuse it?
Yes, we always recommend an inline fuse sized under the 10 amp rating. It protects both the timer and the wiring on that circuit, and it's cheap insurance.
Can I use it for anchor or courtesy lights?
That's a great fit. A delay-off timer is ideal for lighting you want to linger for a minute or two before shutting off automatically, so you're not left in the dark and nothing gets left on overnight by accident.
Is the delay adjustable?
This is a fixed-function delay-off control, not a dial-adjustable timer. There's no pot on it to change the timing. Check Hella's spec sheet for the delay before you wire it in for anything time-critical.
Why pick a Hella Marine part for this?
Hella Marine has been building fit-and-forget electrical gear for boats for decades, with materials chosen for salt, vibration, and heat. For a small part that lives behind your dash and needs to just work, that reputation matters.
