Trigger circuit

An apparatus, having a plurality of triggers, comprising:

• a trigger circuit including:
• a trigger switch, corresponding to one of the triggers, having a first end and a second end, in which the first end of the trigger switch electrically connects to the pad, and the second end of the trigger switch electrically connects to a voltage source, wherein the voltage source has a first voltage value;
• and
• a trigger network, corresponding to a rest of the triggers, in which the trigger network has an impedance value, and has at least one trigger sub-circuit coupled with the pad;
• wherein, when the trigger switch is triggered, due to the impedance value of the trigger network, only the first voltage value can be detected at the pad.

A computer mouse, having at least a left key, a right key and a central key, comprising:

• a trigger circuit including:
• a trigger switch, corresponding to one selected from the left key, the right key and the central key, having a first end and a second end, in which the first end of the trigger switch electrically connects to the pad, and the second end of the trigger switch electrically connects to a voltage source, wherein the voltage source has a first voltage value;
• and
• a trigger network, corresponding to a rest of the left key, the right key and the central key, in which the trigger network has an impedance value, and has at least one trigger sub-circuit coupled with the pad;
• wherein, when the trigger switches are triggered, due to the impedance value of the trigger network, only the first voltage value can be detected at the pad.
