Which plug

One cable to one device. The plug connection at the end of the cable is what determines which device it goes to.

The Surefire/Modlite plug is the light side. A round pin seats into the port on the back of the tail cap. Modlite states it fits Surefire, Arisaka and Modlite Scout bodies, and the Surefire UE and DS00 tail caps.

The Crane Plug is the laser side. It meets the device at ninety degrees so the cable runs along the body rather than straight out of the back, which keeps the installation compact, and it is the smaller of the two, so they are easy to tell apart. The name comes from the Naval Surface Warfare Center at Crane, Indiana, where the standardization work behind it started. Modlite states it 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.

Activation

The button is momentary. The device is on while it is held and off when it is released.

Because the button is momentary, the light returns to dark whenever the hand comes off it, and there is no way to leave it on from the rail. Constant on is a separate act at the tail cap. Some people prefer that, and choose this switch for it.

For a laser, constant on comes from the laser’s own controls. Most have a double tap to constant, and the switch passes it through.

Tail cap options

Constant on for a light is a function of the tail cap. The plug connection seats there, so a tail cap is required and this switch does not include one.

The DS00 button shares the back face with the port, which is why it is small. The UE has nothing on that face, leaving the tail of the light slick.

Cable

4.5″ with either plug, and 7″ with the Surefire/Modlite. Modlite notes the 4.5″ reaches the device from the top rail in most setups.

The switch is molded to the cable and the cable to the plug, so the length is fixed at purchase.

The ModButton and AXON switches

Built from two single leads:

Two single leads is the configuration users most often miss: two devices under independent control, using two switches and two rail positions, or both switches in one dual SNAP mount. The dual lead covers two devices on one press. The AXON puts two devices under one hand on separate buttons, and its light button adds constant on at the rail for the light.

Full power

Older switches were built for 3, 6 and 9 volt lights. Cells moved to 18350, 18650 and 21700, and current draw moved with them. A switch built to the older standard does not pass the draw of current head technology. Modlite puts the typical loss at 15 to 20% of output.

The ModButton Lite passes it, so the light runs at full output. It mounts to a light already owned.

Mounting

All four mounts are alternatives to each other, not additions.

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 is where a laser switch often goes once the light has taken twelve. Which side follows whether the shooter is left or right handed. Rail length and handguard diameter set what is reachable without changing grip.

Handguards vary. A Picatinny rail at twelve is close to universal. Some run Picatinny at twelve, three, six and nine. Some pair Picatinny at twelve with M-LOK on the other faces.

Two switches on one rail sit at some distance from each other. Separation helps with reaching for one and finding the other, and with catching one on gear. The guards raise the sides of the button and reduce the exposed face. A dual SNAP takes the other approach and holds both switches in one mount.

The switch mounts on either side of the rail, which changes the cable routing. Route the cable close to the rail to avoid snags and clear of barrel heat.
