Push button switch with frame releasably coupled to housing - has coupling threaded region with several grooves parallel to housing axis

摘要

The push-botton of the switch is surrounded by a frame releasably coupled to the switch housing. The latter has an outer thread with an annular nut (12) on the end facing the facing the frame. In the thread region (11) are provided several grooves (9) parallel to the housing axis. The frame (6) has sprung protrusions (7) inserted into the grooves, which are held there by the annular nut. Preferably the thread region has four grooves spaced by 90 deg. In each groove bottom is provided a recess (10) engaged by a lug (8) of each sprung protrusion. The free play between the protrusions and the annular nut may be smaller than the height of the lugs. On the housing end, away from the push-button are switching elements in a connecting member, whose terminal, tags protrude from a plane at right angles to the switch long axis.
