I haven't found any compatible clicky switches for the board** A: Most of the low profile mechanical keyboard PCB boards on the market are not compatible with any brand of low profile switches. The XVX L75 keyboard's original switch is OUTEMU(GTMX), and if you are looking for the replacement switch, you can only choose that brand of switch. **Q: I see the switches are hot-swappable, but what brand of switches are sold with this?** A: Those are likely Outemu switches. They’re OK for linear switches - not too clicky **Q: Are the keys prelubed?** A: They are not prelubed, however, they are very smooth and I've had mine for around 8 months without any issue. ## Frequently Bought Together - Womier M84 75% Wireless/Wired Mechanical Keyboard, Compact 84 Keys Hot Swappable Gaming Keyboard, N-Key Rollover RGB Custom Keyboard for Windows Mac PC Gamer (Coral Sea, Gateron Yellow Switch) - XVX Wired Gaming Mouse, 12000 DPI RGB Gaming Mouse with 12 Backlit Modes & 7 Macro Buttons, PC Gaming Mice Support DIY Keybinding, Mouse Gamer Computer Mouse for Laptop PC Mac Windows, Coral Sea --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/428815365-costom-womier-m84-75-wireless-wired-mechanical-keyboard-compact-84](https://www.desertcart.pl/products/428815365-costom-womier-m84-75-wireless-wired-mechanical-keyboard-compact-84) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
