Product Description

The GT04 Mechanical Keyboard Switch 2.5mm Travel is a mechanical keyboard switch designed for thin and light devices. It features a short 2.5mm key travel and an ultra-thin design of only 0.31 inches from the PCB end, making it ideal for laptops with their compact keyboard height requirements. Its smooth actuation and fast response significantly enhance the everyday typing experience.

As a laptop keyboard switch, the GT04 series maintains stable operation in harsh temperature environments (-40℃ to +80℃) and boasts a mechanical lifespan of over 20,000,000 keystrokes and an electrical lifespan of over 20,000,000 keystrokes, capable of withstanding prolonged high-frequency typing and meeting the durability requirements of office and mobile work devices.

Furthermore, this switch is a linear keyboard switch, providing a consistent and smooth typing feel. Meticulously designed by a micro switch manufacturer, the GT04 series combines thinness, longevity, and high reliability in a compact laptop keyboard.
