XA1E-BV Emergency Stop Latch

This is a replacement for the small internal latch inside the IDEC XA1E-BV emergency stop switch, the type commonly installed in Fanuc teach pendants. When a pendant is dropped, this latch is one of the most common failure points, even though the rest of the switch is still usable.

The typical fix is replacing the entire assembly (Fanuc A05B-2255-D001), which often means cost, lead time, and unnecessary downtime. This part allows you to repair the mechanism when everything else is still functional, helping get equipment back up and running faster.

What this part does

It restores the mechanical link between the button and the contact block when the original latch has broken.
