A door opening circuit comprises pipe-shaped housing and a button which can be moved axially in a housing in order to actuate a circuit component connected to the housing. The button is held in a rest position by a force and can be pushed in a direction opposing said force. Perpendicular to the push path of the bottom and pivotable about a pivot mount. A lever is provided perpendicular to the push path of the button and pivotable about a pivot mount. The lever acts upon a circuit component from a position at a distance to the pivotal mount, whereby the button impinges upon the lever between the pivotable mount and the aforementioned position. Another button is located concentrically to the first button on the reverse side of the housing. The pivotal mount is provided with a lever element. The lever can be moved in the direction of the housing longitudinal axis towards the first button. The other button impinges on the lever element and is held by a force in a rest position and can also be pressed in against the action of said force.
A door opener switch with a tubular housing and a button that moves axially in the housing to actuate a switching mechanism that is connected with the housing, whereby the button is held in its idle position by a restoring force and can be pushed in against the action of said restoring force with a lever that is oriented transversely in the displacement path of the button and can be pivoted by the button around a pivot bearing, which lever acts with a point at some distance from the pivot bearing on the switching mechanism, whereby the button is in contact with the lever between the pivot bearing and the point, wherein, on the back side of the housing there is an additional button which is concentric to the first button, the pivot bearing is located in a lever element which can be moved in the direction of the longitudinal axis of the housing toward the first button, the additional button contacts the lever element and the additional button can be held in its idle position by the restoring force and can be pushed in against the action of said restoring force.
