Patent ID: 7385151

Claim:
An apparatus, comprising: a knob having an elongated actuator extending from a lower surface of the knob to an outboard end, the elongated actuator having a fin that terminates before the outboard end of the elongated actuator; a camstack shaft for rotating a camstack used to selectively engage cam followers for controlling operation of an appliance cycle, the camstack shaft including a passageway for receiving the elongated actuator extending from the knob and the camstack shaft having a splines to receive the fin of the elongated actuator, the camstack shaft and the fin of the elongated actuator cooperating to enable rotational movement of the camstack; a switch actuator having a hub and a radial flange, the hub engages the outboard end of the elongated actuator so the actuator is axially moved by depression of the knob; a switch having one contact mounted on one end of a resilient member configured to urge the one contact toward another contact to close the switch; and a slider having a first end and a second end, the first end of the slider contacting the radial flange of the switch actuator and the second end of the slider being coupled to the resilient member of the switch so that depression of the knob moves the radial flange of the switch actuator with respect to the first end of the slider to urge the resilient member and the one contact away from the other contact to open the switch.
