Standard or SYNC

Both options carry two leads and two buttons. Neither changes how many devices the switch activates. What changes is what the angled button covers.

Standard keeps the two devices apart. One button, one device, either on its own.

SYNC adds a combined press without taking anything away. The angled button brings up both at once, and the flat button still activates the laser by itself. That is worth knowing before ordering, because SYNC does not cost you independent laser control.

What SYNC does cost is the ability to activate the light alone. If that matters, Standard is the one.

Two buttons, one hand

That is the reason this switch exists. A light and a laser both reachable without moving the support hand, and without a second switch at a second rail position.

The two buttons are told apart by shape rather than by position. The angled face is the light, the flat face is the laser. Both sit on one housing, so there is no separation between them to find by feel the way there is with two switches mounted apart. Whether the shapes are enough is worth testing with the gloves and gear you actually run.

For two devices on separate rail positions instead, two single lead ModButton Lites give the same independent control with the separation that comes from two mounting points.

Activation

The light button has two actions. Pressure alone gives momentary, with no click: the light is on while it is held. A click sets it constant on, and a second click releases it.

The laser button is momentary only. There is no constant on at the rail for the laser. Most lasers use a double tap to constant from their own controls, and the switch passes it through.

That split is deliberate. A laser left on from the rail is harder to notice than a light.

Which plug

This page is the LINK USB-C plug on the light side. LINK is Unity’s switching system, and the connector is an actual USB-C, not a proprietary interface under a USB-C name.

The laser lead ends in a Crane Plug, which meets the device at ninety degrees so the cable runs along the body rather than straight out of the back. Modlite states the Crane Plug fits the PEQ-15, sold commercially as the L3Harris ATPIAL, along with the B.E. Meyers MAWL and the Wilcox RAIDx. Check the port on your laser before ordering.

For a light already using a Surefire tail cap, see the Surefire plug version.

Tail cap options

The USB-C lead seats at the tail cap, and only one cap takes it.

The Surefire UE and DS00 do not take a USB-C lead.

Unlike the ModButton Lite, the tail cap here is not where constant on comes from. The switch already has it at the light button. The GASCAP is the port, and its button is a second way to reach the same function.

Cable

4.5″ and 7″. Both leads are the same length as each other.

The switch is molded to the cables and the cables to the plugs, so the lengths are fixed at purchase.

The ModButton and AXON switches

Built from two single leads:

This is the only switch in the line that puts two devices on separate buttons under a single hand position. Everything else either uses one button for both, or takes two rail positions to keep them apart.

Note that SYNC appears on the AXON SL as well, where it means something different. The SL has one button, so SYNC there is what gives it a second device. Here both options already carry two.

Mounting

The AXON hardmounts directly to an M1913 Picatinny rail. There is no clamp to remove and no separate mount to buy for a Picatinny handguard.

For an M-LOK surface, the AXON M-LOK mounting plate is the adapter. The ModButton guards and SNAP mounts do not fit this switch; they are ModButton parts and clamp to a different housing.

Placement

Twelve o’clock is common for a white light switch, reachable with the support hand thumb from most grips. Two and ten put it on the side of the rail. Which side follows whether the shooter is left or right handed. Rail length and handguard diameter set what is reachable without changing grip.

Both buttons sit on one housing, so this is one position to settle rather than two. The tradeoff is that position can no longer be used to tell the two devices apart. The angled and flat faces do that work instead.

Both leads route from the same housing, so plan the routing for the light and the laser together. Route close to the rail to avoid snags and clear of barrel heat.
