ABSTRACT:
An improved four-way switch operated by a single manual push button at the end of a control column includes an axially extending shaft mounted to pivot on a stud. The shaft and stud are retained within a housing. An elastomeric washer with a frusto-conically shaped center passage is affixed on the shaft and engages the housing to radially bias the shaft and thereby maintain the shaft in proper axial alignment. Contacts are attached to the shaft and engage selected contacts on the housing when the shaft is pivoted. Guide slots in the housing cooperate with the pivotal shaft to control the direction of pivotal movement of the shaft.
