Patent abstract
A control knob has a body and a lock mechanism. The lock mechanism acts as a safety mechanism or safeguard by biasing the knob in a locked position, thereby preventing the knob from engaging a control stem or other structure on, for example, an appliance. This prevents the knob from inadvertent rotation which may power-on an appliance, or cause a change in a current setting of an appliance which, in certain instances, may have dangerous repercussions.
