摘要 |
A rotary selector switch having a wiper which is arranged on a rotor rotatably held in a cavity formed by a housing and case and is slidingly rotated on the housing base on which are disposed fixed contact elements, thereby to connect electrically at least one of the fixed contact elements to one of the remaining fixed contact elements, in which vertical walls of dovetail portions constituting a ridge projecting from the rotor base are arranged to abut in turn against side walls of ridges extended from an annular ledge arranged at an inner side of the housing corresponding to the rotation of the rotor whereby the rotation of the rotor is stopped; a slot defined in one of the dovetail portions of the ridge arranged on the rotor base is engaged in turn with one of the projections arranged on the housing base corresponding to the rotation of the rotor whereby an audible click may be caught; a slit defined in the housing base between the fixed contact elements disposed thereon aids to cut off a chain of undesirable powder bridging the fixed contact elements one of which is electrically connected to one of the remaining contact elements via the wiper.
