Abstract
A cam-operated timer for a household appliance. The timer includes a rotatable cam-carrying member having cam surfaces, a drive mechanism to rotate the cam-carrying member, a plurality of cam-actuated switches each mounted for engagement with a cam surface, and a textured surface and an audible and/or tactile feedback member. The audible and/or tactile feedback member is positioned to move across the textured surface to generate audible and/or tactile feedback in response to at least manual rotation of the cam-carrying member.

A timer for controlling an appliance, comprising:
- a rotatable cam-carrying member having cam surfaces thereon,
- a timing motor having a rotor that rotates in response to electrical stimulation,
- a drive mechanism for causing rotation of said cam-carrying member in response to rotation of said rotor,
- a plurality of cam-actuated switches, each cam-actuated switch mounted for engagement to a cam surface of said rotatable member for actuation of said switch in response to rotation of said rotatable member, and making and breaking an electrical connection in response to actuation by said rotatable member,
- a textured surface and an audible and/or tactile feedback member, said audible and/or tactile feedback member being positioned to move across said textured surface to generate audible and/or tactile feedback in response to at least manual rotation of said cam-carrying member, said audible and/or tactile feedback member being separate from said drive mechanism and cam-actuated switches of the timer and not making or breaking electrical connections.
