Abstract: An electrical switch the body of which includes a base, and supports an operating member for rotational and axial movement relative to the body. The base is formed with an aperture and a light source support member is received in the aperture. Between the light source support member and the base there is defined a passage therein, in use, a region of an appropriately shaped blocking element can be received. The blocking element, when incorporated in the switch, extends into the path of either axial, or rotational movement of the operating member relative to the body to prevent such movement of the operating member.

Abstract: An electrical switch comprises a body, including a base, an operating member supported by the body for rotational and axial movement relative thereto, an aperture extending through the base and a light source support member received in said aperture. The support member and the wall of the aperture are so shaped that the support member can be located in the base in either of first and second different axial positions relative to the base. The support member includes a blocking element, which in the first axial location of the support member relative to the base extends into the path of either axial or rotational movement of the operating member relative to the body to prevent such movement of the operating member relative to the body. The second location of the support member relative to the base is such that said blocking element lies out of the path of either axial or rotational movement of the operating member so that both movements of the operating member relative to the body are permitted.
