Abstract
A cam-operated timer for a household appliance features lanced switch arm contacts. A contacting surface of at least one switch arm includes a tear in the surface of the switch arm. Adjacent the tear, a first portion of the contact surface is deflected away from the surface of the switch arm in a first direction, whereby a sharp contact edge is created. The sharp contact edge permits the switch arms to make good contact with adjacent switch arms.
