ABSTRACT:
The present invention relates to an ejection switch for a nailer, comprising a valve seat, a gliding seat and a moving bar, allowing for precise controlling of the ejection of nails. The moving bar glides vertically within a gliding seat, with a vertical position that controls a loading state and an ejection state of the ejection switch. The gliding seat glides vertically within the valve seat. After ejecting a nail and after loading for another ejection, the gliding seat respectively moves against the moving bar. Thus the triggering of the loading state and of the ejection state follows the position of the moving bar in a hysteresis-like behavior and unwanted ejection of nails is prevented.
