Sleeve and terminal holder assembly for an axial split-pin tumbler-type switch lock mechanism

In an axial split-pin tumbler-type switch lock mechanism, said mechanism including a lock cylinder, and an operating part disposed forwardly with said cylinder and rotatable about a longitudinal axis extending between front and rear ends of the part, said operating part including a cylindrical head and a shaft having a reduced diameter with respect to the head and extending rearwardly therefrom, said head having longitudinal tumbler bores extending therethrough and disposed radially outwardly of said shaft, a sleeve and terminal holder assembly fixedly secured to said cylinder and comprising:

• a sleeve disposed within and fixedly secured to said cylinder adjacent to said operating part head and with said shaft extending therethrough, said sleeve having longitudinal tumbler bores therein adapted for alignment with said head bores for receiving split-pin tumblers in aligned bores,
• a holder for electrical terminals spaced rearwardly from said sleeve, and
• means fixedly joining said sleeve to said holder in an assembly adapted for insertion in said cylinder as a unit.
