Abstract
A touch pen includes a sleeve, a contact element, a sensing device and a buffering element. The contact element is penetrated through the sleeve and movably relative to the sleeve. The sensing device is disposed within the sleeve. The buffering element is disposed within the sleeve. The contact element and the sensing device are separated from each other by the buffering element. While the contact element is moved in response to an external force applied to touch pen, the impact of the contact element on the sensing device is largely reduced because the contact element and the sensing device are separated from each other by the buffering element. Moreover, since the external force is received by the buffering element, the sensing device can be protected by the buffering element. Consequently, the failure probability of the touch pen is reduced.
