ABSTRACT:
A pushbutton switch is disclosed which includes a pushbutton formed of a synthetic resin to have a recess, and a lever having an attachment portion for fitting into the recess. The lever is formed of a synthetic resin relatively harder than the material of the pushbutton and relatively small in creep contraction rate. The attachment portion has projections thrusting into the wall of the recess so as to prevent the lever from coming out of the recess.
