Stylus pen actuating switch

Claim 2

In combination with a stylus pen, an actuating switch comprising: a first contact; a second contact; and spring means disposed between said first and second contacts, such that when pressure is applied to the stylus pen to actuate the actuating switch, said spring means compresses to simultaneously contact both said first and second contacts to positively actuate the actuating switch and provide a sensed indication of movement to an operator to alert the operator of closure of the actuating switch.

Claim 3

The actuating switch of claim 1 wherein said spring means is essentially circular in shape having an outwardly concave exterior surface disposed adjacent said first contact and an inwardly convex interior surface disposed adjacent said second contact, such that upon compression, said spring means becomes essentially flat.

Claim 4

The actuating switch of claim 2 and further including: insulating means disposed between said first and second contacts for receiving said spring means, such that a predetermined area of said interior surface of said spring means contacts said second contact upon actuation of the actuating switch.

Claim 5

A stylus pen for use with a data tablet comprising: a housing having first and second ends; means disposed at said first end of said housing for engaging the data tablet and for slidable movement within said housing; first and second switch contacts disposed within said housing; said first switch contact being interconnected to said engaging means; said second switch contact including stop means for engaging said housing, such that said second switch contact remains fixed within said housing; and spring means disposed between said first and second switch contacts to normally maintain said switch contacts in a spaced apart relation, such that when pressure is applied to said housing said engaging means moves inwardly within said housing to cause said first switch contact to move toward said second switch contact and thereby compress said spring means enabling simultaneous contact between said spring means and said first and second switch contacts to positively actuate said switch contacts and provide an indication to an operator of switch closure.

Claim 6

A stylus pen for use with a data tablet comprising: a housing having first and second ends; means disposed at said first end of said housing for engaging the data tablet and for slidable movement within said housing; first and second switch contacts disposed within said housing; said first switch contact being interconnected to said engaging means; said second switch contact including stop means for engaging said housing, such that said second switch contact remains fixed within said housing; and spring means disposed between said first and second switch contacts to normally maintain said switch contacts in a spaced apart relation, such that when pressure is applied to said housing said engaging means moves inwardly within said housing to cause said first switch contact to move toward said second switch contact and thereby compress said spring means enabling simultaneous contact between said spring means and said first and second switch contacts to positively actuate said switch contacts and provide an indication to an operator of switch closure.

Claim 7

The stylus pen of claim 4 wherein said spring means comprises: compression spring means essentially circular in shape having an outwardly concave exterior surface disposed adjacent said second switch contact and an inwardly convex interior surface disposed adjacent said first switch contact, such that upon compression said spring means becomes essentially flat to simultaneously contact said first and second switch contacts.

Claim 8

The stylus pen of claim 4 wherein said housing further includes: shoulder means for engaging said stop means, such that said spring means applied a force to said shoulder means upon compression of said spring means.

Claim 9

The stylus pen of claim 4 and further including: insulating means disposed between said first and second switch contacts for receiving said spring means, said insulating means having a centrally disposed aperture for receiving said first switch contact.

Claim 10

The stylus pen of claim 6 wherein said stop means includes: a plurality of radially extending arm means for engaging said shoulder means of said housing.

Claim 11

The stylus pen of claim 7 wherein said insulating means includes means for receiving and retaining said stop means.

Claim 12

The stylus pen of claim 7 wherein said insulating means includes a plurality of apertures for receiving a plurality of radially extending arm means of said stop means.
