Compare Gateron Optical Switch V2 and Kailh Pro Switch sets for your mechanical keyboard. Learn key differences, trade-offs, and which fits your typing style.
Quick Answer
Choose the Gateron Optical Switch V2 if you own a compatible optical keyboard and want a smooth, fast response. Choose the Kailh Pro Switch if you prefer a traditional mechanical feel with more tactile feedback.
Compatibility: Optical vs Mechanical
The biggest difference between these two switch sets is the technology behind them. Gateron Optical Switch V2 uses light-based actuation, which requires a keyboard with an optical hot-swap socket. Kailh Pro Switch is a traditional mechanical switch that works with standard mechanical hot-swap boards.
If you already own a keyboard, check whether it supports optical switches or standard mechanical switches. Buying the wrong type means the switches won't fit or function. If you're building a new keyboard, decide which technology you want before choosing the switch set.
Feel and Performance Trade-offs
Optical switches offer faster response times because they use light instead of metal contacts. That can be a plus for gaming, but some typists find them less tactile than mechanical switches. Kailh Pro Switch provides the classic mechanical feel with a distinct bump or click, which many typists prefer.
Both sets include 110 switches, so you can cover a full-size board with spares. Consider your priority: speed and smoothness versus traditional tactile feedback.
