Brief review of TTC Flame Snow Switch & Flame Purple Switch: A combination of two swords, good feel and hearing

As a well-known domestic switch manufacturer, TTC has well-known linear switches such as gold powder switches and fast silver switches. With its excellent feel performance, it has also won praise from many users in the keyboard circle. TTC has carried out a large-scale update of its products this year. Through a series of updates and upgrades such as product structure optimization, new materials, and new processes, it has further improved the feel feedback and sound performance. In terms of new products, TTC has also recently launched two new switches, which are named Lie Yan Xue and Lie Yan Zi respectively. Next, let’s follow the author to see how these two switches perform.

　　TTC烈焰雪轴&烈焰紫轴沿用MX轴体结构方案，轴体参数部分保持一致，仅在整体配色、导光结构上有所不同。烈焰雪轴采用了白色轴座、轴心搭配透明轴盖方案，烈焰紫轴则为深紫色的轴体色彩搭配，在外观上还是非常容易分辨的。同时，由于轴盖材质不同，烈焰雪轴采用了传统的一体式凸透镜轴盖方案，而烈焰紫轴由于采用半透轴盖，为了提升透光表现则采用了聚光镜导光结构。

The TTC flame snow shaft adopts a high-transparency shaft cover, combined with the all-white shaft center and shaft seat, which looks crystal clear, pure and flawless, and the excellent appearance performance also brings better visual performance. The shaft seat part adopts a three-legged scheme, which can be easily compatible with most of the mechanical keyboards currently on the market that use the MX structure shaft body, and is also friendly enough for users to replace. The shaft cover part follows the four-corner buckle scheme, which is tightly fixed with the shaft seat and has better dust-proof performance. The double-sided dust-proof wall can also make the hand feel more stable. The shaft adopts a brand new POK material, which has better wear resistance and ductility, and the noise performance is also slightly better than that of POM material. Combined with the rich internal grease lubrication, the smoothness of pressing, feel feedback and knocking Sound is better. The light guide structure of the convex lens is compatible with mainstream SMD lamp beads, and with the fully transparent shaft cover, it also makes the lighting effect more uniform and natural.

The TTC flame purple switch adopts a dark purple color scheme for the switch body, and the slightly lighter color scheme of the switch center also brings a progressive visual impression, making the switch body more layered. The matching method of the tripod axle seat and the four-leg snap-on axle cover also ensures the feel and durability of the axle body. The internal structure of the flame purple switch is the same as that of the flame white switch. Both switches are equipped with a 23mm single-section long spring. The feel feedback is linearly balanced. Tactile performance. In order to solve the problem of poor light transmission effect of the translucent shaft cover, the flame purple shaft is equipped with an independent condenser light guide structure, which has higher light guide efficiency and luminous flux, and can also improve the divergence effect of the light, making the light performance softer Uniformity, further improving the overall lighting effect performance.

　　TTC烈焰雪轴&烈焰紫轴采用了相同的轴体参数，触发压力42gf，有着1.6mm的触发键程和3.6mm总键程，整体参数方案还是偏向于轻快的手感表现。线性手感方案配合23mm单段长弹簧，手感反馈顺滑轻盈，触底回弹迅捷跟手，手感紧实触底稳定，声音表现也较闷脆。轴体内部丰富的脂状润滑，提升按压手感的同时有着更好的杂音抑制表现，整体表现还是非常出彩的。轴体内部金属部件同样采用了防氧化涂层镀银工艺，可以避免铜质氧化，降低轴体失灵、损坏几率，更领这款轴体拥有约一亿次的触发寿命，进一步提升了用户的使用体验。适中的触发压力与触发键程，也能避免日常使用中出现误触的情况，较短的触发键程也也让这两款轴体可以更好的兼顾日常使用或游戏场景下使用。

　　TTC烈焰雪轴&烈焰紫轴两款轴体在灯光表现上相差并不太大，烈焰雪轴采用了PC高透材质轴盖，配合凸透镜灯位方案，灯光发散效果还是比较不错的。烈焰紫轴则是采用了独立的聚光镜导光结构，可以降低半透轴盖对于灯光发散的干扰，带来更好的灯光表现。两种不同的灯光方案都有着不错的散射效果，灯光自然柔和、均匀明亮，键帽间隙也完全被灯光填满，在灯光渲染以及视觉观感上都有不错表现，再配合上RGB灯珠丰富的颜色，使视觉观感更加绚丽多彩。

Summarize:

　　TTC烈焰雪轴&烈焰紫轴两款轴体都有着轻盈顺滑的按压表现，手感反馈清晰舒适，轻柔适中的触发压力也能减少误触情况的出现，更好的兼顾办公、游戏等不同场景使用，也能更好的缓解长时间使用带来的疲劳感，对于用户还是足够友好的。不过烈焰紫轴的聚光镜方案对于部分键帽还是一些兼容问题，容易出现卡键问题，用户在选购时候还是要注意一下的。TTC烈焰紫轴将首发搭载在珂芝（KZZI）、雷神旗下键盘上，TTC烈焰雪轴则首发搭载在游戏动力旗下键盘上，喜欢的用户不妨关注一下。
