description PCB (Hot-Swap Compatible) Overview
A hot-swap compatible PCB (Printed Circuit Board) is a circuit board design that allows electronic components to be replaced without desoldering, commonly implemented in mechanical keyboards. These specialized PCBs feature built-in sockets that hold the pins of mechanical switches, enabling users to swap switches using only a switch puller tool. This design simplifies customization, troubleshooting, and modification of devices by allowing components to be changed quickly without specialized equipment or soldering skills. Hot-swap PCBs have become particularly popular among keyboard enthusiasts who experiment with different switch types.
help PCB (Hot-Swap Compatible) FAQ
What does hot-swap compatible mean for a mechanical keyboard PCB?
A hot-swap PCB has sockets that let you install compatible switches without soldering each switch to the board. This makes it easier to change switch types, but the sockets still need the correct switch pin layout.
Can I put any mechanical switch into a hot-swap PCB?
No. Most boards support common MX-style switches, but compatibility depends on the socket type, switch pins, plate, and PCB layout. Some low-profile or unusual switches require a different board.
Does a hot-swap PCB support both 3-pin and 5-pin switches?
Many hot-swap boards accept 3-pin switches, while 5-pin switches may need matching PCB holes or removal of their plastic locating pins. Check the board's layout before buying a complete switch set.
Is a hot-swap PCB better than a soldered PCB?
It is more convenient for experimenting and replacing switches because no desoldering is needed. A soldered PCB can offer a fixed, robust build, but changing switches requires tools and more work.
