Dome module of high-temperature-resistant key

The utility model discloses a dome module of a high-temperature-resistant key. Wherein the dome elastic sheet is adhered to one side of the PET film through a double faced adhesive tape, and the salient point is pressed on the other side of the PET film. The dome module can resist the high temperature of 300 DEG C at most, and the dome die holder adopts a modular design, so that the dome module isconvenient to produce and assemble accurately; the convex points are arranged on the outer side of the PET film, the convex points are pressed firstly to enable the middle of the dome elastic piece to deform, then a circuit is triggered to be connected, by means of the design, the key pressing accuracy can be improved, and the situation that the elastic piece cannot be triggered to deform due toinaccurate pressing positions is avoided. 本实用新型公开了一种耐高温按键的dome模组，包括PET膜、通过双面胶粘贴在PET膜一侧的dome弹片、以及压合在PET膜另一侧的凸点，所述的凸点正对dome弹片中心，本实用新型的dome模组最高能耐300℃的高温，而且dome模座采用模块化设计，便于生产和精准地装配；通过在PET膜的外侧设置凸点，先按压凸点来使dome弹片的中部变形进而触发线路接通，采用这种设计能
