A compact control-type optical switch includes a control knob provided on the obverse surface of a lid; a switching member slidable right and left in a housing; a substantially trapezoidal prism disposed on the undersurface of the switching member; and a plurality of optical receptacles provided on the bottom of the housing. The control knob is actuated, and thereby the prism slides on the optical receptacles to change an optical path.
