ABSTRACT:
A vehicle power seat switch designed to prevent a knob from vibrating has a switch body incorporating plurality of switch elements and having projecting shafts movably disposed to drive the switch elements, and at least one knob having pairs of wall portions formed on the reverse side, each pair of wall portions facing each other with one of the projecting shafts interposed therebetween, the knob being moved to operate each of the switch elements to adjust the position of the vehicle seat. Elastic extensions are integrally provided on one of the pairs of wall portions so as to be able to contact the outer circumferential surface of the corresponding one of the projecting shafts. It is thereby possible to reduce the noise level at a comparatively small parts cost.
