The Rotary N413-1 electrical control component is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7503-65S, it is the genuine Rotary part — same part number, same fit, and same working specification as the one already on your lift. Ordering the Rotary electrical control component from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.
Specifications
- Part number: ALS-7503-65S
- Brand: Rotary
- Type: Genuine OEM electrical control component

- Lift type: 2-post lift
A small electrical fault left alone becomes a bigger, more expensive one. A loose lug that arcs will eventually burn the terminal, then the wire, then the component it feeds. A chattering contactor hammers the motor with partial voltage until the windings cook. Chasing down a hot connection or a pitted switch early is a cheap fix; letting it run until it melts something takes out the motor or the whole control box.
The electrical side of a lift is what turns wall power into lifting motion: the disconnect and breaker feed a switch or push-button, which energizes a contactor, which sends power to the motor that spins the pump. Limit switches and safety cutoffs sit in the circuit to stop the lift at the top or if an overhead bar is hit. When the lift won't run, the fault is somewhere in that chain — and it's often electrical, not hydraulic.

Replacing your electrical control component
Most lift electrical work follows the same order: verify power is off, trace the circuit from source to motor, replace the failed part, then power up and test both operation and the safety stops. Guessing at where in the chain the fault lives wastes time and risks the wrong part. For that reason the full procedure is worth reading first. Not sure on the procedure? Find your lift in our parts lookup or call and we will walk you through it.
Find the right part for your lift
Not certain this is the exact part your lift needs? Start with your lift's model and serial off the data plate, then open our Rotary parts lookup to see the visual parts breakdown for your model — the exploded drawing with every part numbered and priced. If your plate is missing or unreadable, our guide to finding your model number walks through where to find it, or send us a photo and we will identify the lift for you.
Signs of an electrical fault
Check the push-button or control switch for hold-to-run behavior and clean action. The lift should move only while the button is held and stop the instant it's released. A button that sticks, that runs on after release, or that needs several presses to make contact is worn or damaged. Because the control is a safety part, a switch that won't reliably stop the lift is a replace-now item.
Parts commonly replaced at the same time
Electrical faults often involve more than one component — a failed contactor can take a relay or a switch with it, and worn wiring shows up alongside. While the panel is open, check the companions so you are not back in there next week. Tell us your lift's voltage and phase and we will match the related parts.
Safety notes
Isolate the lift from power before you touch any electrical component — lock the disconnect out if the shop has one. Lift control circuits mix line voltage with low-voltage safety inputs, and a miswire can defeat an overhead shutoff or a lock. If you are not confident on the control system, stop and call for help before something moves unexpectedly.
Before you order
Have the data plate in front of you — model, serial, voltage, phase — before ordering electrical parts. These details decide which relay, switch, or motor fits, and getting them wrong means a return. If the markings on the old component are readable, share them and we will match exactly.
Confirm this is the right part before you order
Lift manufacturers revise parts mid-production without changing the model name, so the same lift bought two years apart can take two different revisions of the same component. Before you order, find the model plate on the lift — on most 2-post lifts it rides on one of the columns at eye level, on 4-post lifts it is usually on a column or the power-unit side runway — and note the full model number and serial. The serial dates the lift to a production run, and that is what decides which revision fits.
If the plate is painted over or missing, take a photo of the part you are replacing next to a tape measure and send it to us. Between the dimensions, the mounting pattern, and what lift it came off of, we can almost always identify the exact part before you spend money on the wrong one.
Why buy your Rotary electrical control component from Auto Lift Services
We install, inspect, and repair Rotary lifts every week — the ALS-7503-65S is a part we handle in the shop, not a random SKU we drop-ship. The phone answers if you have a question mid-install — call 800-674-9302 — and every part ships genuine, no aftermarket substitution unless you ask for it.
About this n413 overhead switch
Every order for the n413 overhead switch starts with a fitment confirmation. Two lifts of the same model can carry subtle revisions between production years, and a component that fits a rev-A lift may not fit a rev-B lift built two years later. Before your card is charged we verify the piece against the parts breakdown for your specific lift serial number. That five-minute step is the difference between the part arriving and being installed the same afternoon versus the wrong piece showing up and the shop losing a day of billable work.
Technical specification & installation notes
Technical specification matches the OEM published dimensions to within manufacturing tolerance. When a shop installs the n413 overhead switch correctly, the lift returns to factory-rated performance immediately — no break-in period, no cycle-count adjustment required. The lift's safety systems (mechanical locks, hydraulic pressure relief, and electrical interlocks) treat a correctly-installed replacement exactly as they would treat a factory-original component during initial commissioning. That parity is what lets us honor warranty coverage without asking for the lift's full operating history.
Shipping & ordering
Shipping runs 3-5 business days on standard ground to the lower 48 states. Expedited overnight and two-day options are available; call 800-674-9302 before ordering to quote expedited freight. We stock the n413 overhead switch in Iowa and ship same-day for orders confirmed before 2 PM Central. Orders that come in later than that or on a Friday afternoon pick up on the next business day. A tracking number gets emailed to the address on the order the moment the package leaves our dock.
Warranty coverage
Return policy on the n413 overhead switch follows our store-wide standard: all parts sales are final; exchanges only if the piece arrives defective. In the case of a defective delivery, ship the failed piece back to us at your cost, we verify the defect on receipt, and ship a replacement at ours. Wrong-item deliveries where we made the shipping error follow a different path — we reimburse the return shipping cost and cover freight on the correct part. Contact [email protected] with the order number to start either process.
Cross-reference & fitment
Alternate applications for the n413 overhead switch sometimes exist. Where a common part fits multiple lift models across a manufacturer's catalog, cross-reference sheets show the compatible models explicitly. If you are consolidating parts stock and want to know which of your lifts the piece covers, email the request to [email protected] with a list of the lift models in your bay — we return a compatibility grid showing which lifts accept the replacement and which need a different number.
Questions about the n413 overhead switch? Call our parts desk at 800-674-9302 or email [email protected]. We ship nationwide from our Iowa warehouse and answer fitment questions within one business day.
