ABSTRACT OF THE DISCLOSURE A multiple position, multiple contact key switch, and method of constructing same, including an electrical contact module having a housing defined by first and second separable housing members which snap together in a direc- tion perpendicular to the longitudinal rotational axis of the key switch. The first and second housing members each carry contact sets which alternate with one another along the longitudinal axis. Each housing member includes posts which extend towards the opposing housing member, to maintain the desired positions of the elements of the contact sets carried by the opposing housing member. An arbor is mounted for rotation within the housing, with the arbor having cams spaced along the rotational axis for actuating the contact sets. A halo module and a lock module form a subassembly which is coupled with the elec- trical contact module, with adjacent ends of the lock module and electrical contact module engaging to transmit rotary motion of the lock module to rotary motion of the arbor.
