A multi-stage switch with a common actuating element and at least two switch elements for making contact provides that the switch elements are disposed next to each other above contact elements of a circuit board which they bridge in the closed state. The actuating element for the switch is movably disposed above the switch elements in such a way that the switch elements respond sequentially when the actuating element is depressed. Such a multi-stage switch can be produced cost-effectively with simple structural means, can be universally used, is easy to operate, maintenance free to the greatest extent and operates dependably.
