Abstract

1. A push-button switch having a contact carrier (1), parallel to which there is disposed a sheet (3) of resilient, electrically insulating material which comprises a resilient tongue (4) which is punched free and which is permanently bent at an acute angle at its foot (10) in relation to the plane of the sheet (3) and carries an opposite contact (5) which is lifted from a contact (2) on the contact carrier (1), and having an adjustable actuating element (7) which is disposed above the contact (2, 5), characterised in that the actuating element (7) is of dome-shaped construction and that the resilient tongue (4) is lifted from the contact carrier (1) in the region of the opposite contact (5) and is bent into the dome.
