Abstract: An improved push button assembly including means for facilitating the mounting of the push button assembly to a mounting panel through an opening therein and from the front side thereof. The mounting means is comprised of first and second substantially flat resilient members. Each member has one end thereof fixed to respective opposite sides of the push button housing and another end thereof extending toward the front of the push button and biased away from the plane of the respective adjacent side of the housing. Each of the first and second members has a plurality of fingers forming the other end, wherein the plurality of fingers include a pair of end fingers and additional fingers intermediate the end fingers.

Abstract: A push button assembly including an operating unit and a switch unit having an enclosure. The operating unit is comprised of a housing, fastened to the switch unit enclosure, and having a hollow interior section. The operating unit is further comprised of a collar member having one end positioned within the interior section of the housing and another end extending outward therefrom, and a mushroom head fixed to the other end of the collar member. Also provided is an actuating plunger having one end mechanically coupled to the one end of the collar member and having another end coupled to the switch unit. Further provided are means for maintaining the collar member in a first position and means for maintaining the collar member in a second position.

Abstract: A rotary lever operated limit switch for indicating when a device reaches a limiting position. The switch is comprised of a motion converter at least partially disposed within a first portion of a housing, and a switch assembly disposed within the interior of a second portion of the housing. The motion converter is comprised of a lever having one end adapted to engage the device, and a shaft assembly having one portion thereof attached to the other end of the lever and another portion thereof for providing a switch motion to open and close contacts of the switch assembly upon movement of the shaft assembly and the lever. A first means is provided for restoring the shaft assembly towards its initial position from a position within a range defined by a first predetermined position and the initial position of the shaft assembly. A second means is provided for restoring the shaft assembly towards its initial position if the shaft assembly exceeds the above defined range.
