The Moroso 74122 Universal Momentary Switch and Cable Kit provides a heavy-duty push-button or toggle activation solution for electric fuel pumps, starter solenoids, line-locks, trans-brakes, and other temporary-activation circuits in race cars and performance street vehicles. It's the go-to switch for drag racers building clean, safe electrical controls.

This kit includes a momentary switch rated at 30 amps continuous at 12 volts DC, a 12-foot color-coded 14-gauge primary wire lead, spade terminals, and a switch mounting bracket. The switch body is sealed against dust and moisture, and the spring-loaded momentary action ensures positive engagement with a crisp tactile feel. The wire bundle includes a ground loop for secure chassis grounding.

Integration into any 12-volt system is straightforward — wire the switch inline with your device's power circuit or relay trigger. The included bracket mounts to any flat surface through a single 7/8-inch hole. The long 12-foot lead gives you flexibility to place the switch where it's reachable inside the cockpit or mounted discreetly under the dash.

Don't trust cheap switches with critical race functions. Get the Moroso 74122 Universal Momentary Switch Kit and build your electricals the right way.

Frequently Asked Questions

Can the Moroso electrical switch handle the amperage draw of my electric fan or fuel pump?

The Moroso electrical switch is rated for a specific amperage and voltage that varies by model. Heavy-duty Moroso switches can handle up to 20 to 40 amps at 12 volts DC making them suitable for electric fans, fuel pumps, and auxiliary lighting. Always verify the continuous current rating of the Moroso switch against your device's draw before installation. Using a relay in conjunction with the Moroso switch is recommended for high-current applications exceeding the switch rating.

Does the moroso electrical switch weatherproof for use in engine bay or exterior applications?

The Moroso electrical switch features a weather-resistant or waterproof design depending on the specific model. Sealed Moroso switches use rubber boots or internal gaskets to prevent moisture ingress when mounted in exposed locations. If you are installing the Moroso switch in an engine bay or on the exterior of the vehicle choose a model specifically rated for weather exposure. Non-sealed Moroso switches should be mounted inside the cabin or in a protected location.

What mounting hole size is needed for the Moroso electrical switch in my switch panel?

The Moroso electrical switch requires a specific mounting hole diameter typically ranging from 3/8-inch up to 7/8-inch depending on the switch style. Standard toggle switches from Moroso use a 1/2-inch or 5/8-inch mounting hole with a locking nut for secure installation. The Moroso switch comes with the necessary mounting hardware for a clean professional appearance. Measure your panel thickness and available clearance behind the panel before selecting your switch.

Can the Moroso switch control multiple accessories simultaneously with a single toggle?

Some Moroso switches feature multiple poles or a dual-circuit design that allows controlling two accessories with a single toggle. A DPDT Moroso switch can independently switch two separate circuits at the same time. This is useful for applications like paired off-road lights or dual cooling fans that need to operate together. Check the switch specifications to confirm the pole and throw configuration matches your wiring plan.

How do I wire the Moroso switch with an LED indicator light for night visibility?

The Moroso switch includes terminals for both the main load circuit and the integrated LED indicator. Connect the load wires to the switched terminals and the LED power to the accessory terminal that is live when the switch is on. The LED ground wire connects to the same ground as your accessory circuit. The Moroso switch LED is typically rated for 12 volts and includes a built-in resistor so no external resistor is needed for the indicator.
