BUTTON GREEN KNOB 800T-N246G

A push-button (also spelled pushbutton) or simply button is a simple switch mechanism to control some aspect of a machine or a process. Buttons are typically made out of hard material, usually plastic or metal. The surface is usually flat or shaped to accommodate the human finger or hand, so as to be easily depressed or pushed. Buttons are most often biased switches, although many un-biased buttons (due to their physical nature) still require a spring to return to their un-pushed state.

In foodservice equipment, a knob may be as simple as a push button or "palm button". A control knob is a rotary control used to provide input to a device when grasped by an operator and turned, so that the degree of rotation corresponds to the desired input . Such knobs are one of the most common components in restaurant equipment control systems and are used to modulate a wide variety of settings such as temperature, viscosity, speed and more.
