During enforcement, this switch is located on the outside surface of keyboard body, the electric capacity that this switch is connected with switch for manual switchover.

During enforcement, the utility model also comprises a variable resistor, and this variable-resistance end is connected with positive source, and the variable-resistance other end is connected with thump perception chip.

During enforcement, the utility model also comprises a variable resistor, and this variable-resistance end is connected with positive source, and the variable-resistance other end is connected with an end of this switch.

During enforcement, this variable resistor also comprises a knob, and knob is located on the outside surface of this keyboard body, and this knob is for this variable-resistance resistance value of manual adjustment.

The utlity model has following advantage:

The utility model can be adjusted the duplicate delays of thump perception circuit separately, to reach the execution command reaction time of dynamic change by the keyboard input.

The utility model can be adjusted the repetition rate of thump perception circuit separately, to reach dynamic change is continued repeatedly input instruction by keyboard execution speed.

The utility model can be adjusted the repetition rate and the duplicate delays of thump perception circuit simultaneously, to reach dynamic change is continued repeatedly input instruction by keyboard execution speed and the execution command reaction time.

For ease of more deep understanding being arranged, be specified in the back now to the utility model:
