摘要： A push button switch mounted on a conductor-carrying insulator plate includes a push button to which an external operating force can be applied; an electrically conducting, resilient switch element carrying a movable contact and arranged on the plate within the operating range of the push button for effecting at least an indirect transmission of the operating force to the switch element; and at least one fixed contact carried by the plate. In the operating position the movable contact is in engagement with the fixed contact. The switch element is constituted by a planar sheet member having a central zone bounded by two parallel edges and carrying the movable contact, and strip-like legs integral with the central zone and extending from the edges towards the insulator plate at an inclination with respect to the central zone that is greater than 90.degree.. The legs are supported at least indirectly on the insulator plate at conductor-free portions thereof. Alternative embodiments include the use of a common sheet member having stamped flexible contact areas integral therewith incorporating the design features of the singular switch element.
