It can be pushed back into the body of the device when force on the plunger exceeds the spring force being applied. It would also have to be mated with a far more elaborate and costly latch mechanism. Magnetic detents are most often used to divide a shaft rotation into discrete increments. Stepper motors rely on magnetic detents to retain step location when winding power is removed. To resist movement (or when creating incremental steps), methods are employed which include a spring-loaded ball detent that locates in small incremental depressions, or a piece of spring steel that snaps into position on flat surfaces or shallow notches milled into the shaft or wheel. The spring force is applied to a ball at the end of the spring plunger body, especially suited for quick detent action. Standard spring plungers offer long travel and several material and design options, including a range of plunger nose designs and spring-force options. Choose from our selection of ball detents, including slotted ball-nose spring plungers, press-fit ball-nose spring plungers, and more. Please let us know here why this post is inappropriate.
