Abstract: An electric switch for toys comprises a stationary member and a member rotatable with respect to the stationary member. The stationary member includes a plurality of electrical connections in the physical form of fixed, variable configured contacts with integral terminals. The contacts are bridged by conductive pattern(s) forming part of the rotatable member. Circuits are broken or made which are dependent upon the position of the rotatable member. The rotatable member includes a coupling, preferably a cruciform hole for detachably mounting a protruding lever or protruding shaft. The rotatable member can be rotated between a plurality of premarked positions when the lever or shaft is mounted within the coupling hole. The switch may be used as a building block component.
