Tracker action touch for keys in a keyboard musical instrument

A key action for an electronic musical instrument for simulating a mechanical-type tracker action including a key supported above a key bed by a pivot pin having a guide pin for limiting horizontal movement of the key but allowing vertical movement thereof;

• a return spring fastened between a key tension adjusting means mounted to the key and said key bed;
• and a key return limiting means for returning the key, upon release thereof, to its normal or rest position, the improvement comprising:
• a key switch means located at the distal end of the key having first and second contact means for establishing an electrical contact on the depression of the key mounted in a spaced-apart relation but in close proximity to each other and mounted with said first contact means in touching relation to the distal end of the key, said first contact means having a forward facing protrusion for retarding the vertical movement of the key until sufficient pressure has been exerted on the key to cause a toggling of the key as the retarding force of the first contact means is overcome while said electrical contact is maintained;
• whereby the key switch means provides both an electrical contact and a tracker action in a single means.
