A timer for controlling an appliance includes a bell chime assembly having a striker, a torsion spring, and a bell. The striker is secured to the torsion spring. The timer further includes a cam follower operatively coupled to the torsion spring. The cam follower is operatively associated with a cam assembly which includes a first cam and a second cam. The first cam and the second cam are configured such that during manual setting of the timer, the torsion spring is prevented from deflecting by an amount sufficient to cause the striker to contact the bell whereby relatively quiet manual setting of the timer is enabled.

Apparatus for permitting quiet manual setting of an appliance timer

A timing mechanism having electrical switches opening and closing in response to power driven rotating cams. The electrical switches are composed of fixed and movable electrical contact blades which include electrical contacts carried on the blades. For those blades which are switching currents of two amperes or less (120 VAC) a protuberance on one and/or both the fixed and movable blades may form the contact.
