ABSTRACT:
The hub of a camstack is in the shape of a cone. There are ribs carried on the cone surface with the ribs having cam surfaces that are substantially parallel to the cone surface. The camstack is particularly adaptable for actuating a plurality of individual switches in a direction at an angle to the central axis and to the lines normal to the central axis. The individual switches are carried by a single common support member. The camstack permits the building of less expensive, smaller and more reliable appliance timers.
