75 hot swap keyboard

Most 75% models use fully hot‑swappable PCBs or plates that accept both 3‑pin and 5‑pin mechanical switches. Product listings often note a switch/keycap puller is included so you can replace switches without soldering.

Many models use a multi‑layer acoustic approach — for example, gasket mounting plus layers such as Poron foam, IXPE switch pads, PET sound layers, and silicone bases — to absorb shocks and reduce key noise for a quieter typing feel.

Typical features include a gasket‑mounted 75% layout with hot‑swappable switch sockets (some listings note 1.2mm PCBs and pre‑lubed switches), multi‑layer acoustic padding, RGB backlighting, and a multifunction knob. Many models also offer tri‑mode connectivity (Bluetooth, 2.4GHz, USB‑C) and often list a built‑in rechargeable battery around 4000mAh.

Tri‑mode connections are common: Bluetooth (often Bluetooth 5.0), 2.4GHz wireless, and USB‑C wired. Many models can pair multiple devices and switch between modes for PCs, tablets, phones, and consoles.

Power setups vary by model. Several list a built‑in rechargeable battery around 4000mAh for long runtimes, while other product details mark the battery as optional or note that a lithium‑ion battery may be required/installed for some units.

Some models use side‑printed or double‑injection PBT keycaps. RGB backlighting with millions of colors and multiple preset effects is common, and a few listings note south‑facing LEDs so the backlight shows through the legends.

Many offer programmable software or drivers for RGB lighting, macro recording, and full key remapping. Some documentation notes that drivers are supported only on Windows when the keyboard is in wired mode.
