Abstract
An actuating switch (30) is provided for a stylus pen (10). The actuating switch (30) includes a first contact (74) and a second contact (78). A spring (100) is disposed between the first contact (74) and the second contact (78), such that when pressure is applied to the stylus pen (10) to actuate the switch (30) the spring (100) compresses to simultaneously contact both the first contact (74) and the second contact (78) to positively actuate the switch (30) and provide a sensed indication of movement to an operator to alert the operator of closure of switch (30).
