摘要：
A device comprises a retractable shaft； a shaft biasing spring； and an actuator button. The retractable shaft is biased away from the actuator button by the shaft biasing spring. A magnetic attracting force is created between the retractable shaft and the actuator button upon actuation of the actuator button. Before actuation, a distance between the actuator button and the retractable shaft is great enough that the magnetic attracting force is less than a biasing force of the shaft biasing spring such that the retractable shaft is biased away from the actuator button. Upon actuation, the actuator button is depressed to make the distance between the actuator button and the retractable shaft sufficiently small such that the magnetic attracting force is greater than the biasing force of the shaft biasing spring to allow the retractable shaft to be biased towards the actuator button.
