Specific embodiment

The technical solution of the utility model is described further below in conjunction with the accompanying drawings.

Such as Fig. 2, keyboard of the present utility model is with touch control plate function integral type thin film switch including the first key breakover structure 1 With the second key breakover structure 2, wherein, the first key breakover structure 1 and the key mapping of keyboard correspond, for realizing key The signal input of disk button, the second key breakover structure 2 and the key mapping of Trackpad button correspond, for realize Trackpad by Key signals input.

By the way that the first key breakover structure 1 and the second key breakover structure 2 are integrated on same thin film switch, this is thin Membrane switch can simultaneously realize keyboard input and Trackpad key-press input, control respectively with traditional two thin film switches of employing Keyboard is turned on to be compared with the conducting of Trackpad button, and reduce touch-control plate thin film switch is fabricated separately operation, can be effective It is cost-effective.

Such as Fig. 3, the keyboard may include conductive circuit layer 3 and lower conducting wire with touch control plate function integral type thin film switch Layer 4, wherein, upper conductive circuit layer 3 includes being led in the key mapping one-to-one multiple first of upper conducting wire 31 and keyboard Logical point 32 and with firing point 33 in the key mapping one-to-one multiple second of Trackpad button, firing point 32, second on first Upper firing point 33 is electrically connected respectively with upper conducting wire 31, such as Fig. 4 a；
