No, at the current time, there is no way to add one of our push buttons without also providing welded studs to which to attach it.

How can I add a keyswitch if I don’t already have mounting studs?

If you can use one of our standard barrel-type locks, and if the box is at least 2.75” deep and if there is sufficient room for the device on the faceplate, our PB13 style keyswitches will mount quickly and easily even if there are no factory weld studs. The only field modification required is to drill a round hole .75” in diameter. The kit will come with adhesive-backed anti-rotation plates for either horizontal or vertical mount, and a surface-mounted 1.375” diameter escutcheon for identification. These are available on-line in the Parts Department.
