Abstract
Abstract A control button unit with a block element design includes an actuator (1) having a manually operable plunger (6), which is preferably cylindrical and hollow for the purpose of interior illumination, and a coupling piece (9) having several plug-in locations for receiving electrical block elements (10 and 12) parallel and next to one another. The block elements may include a pair of switching elements (10, 12) with differing contact arrangements and a lighting element (11) to illuminate the interior of the plunger. The block elements have movable members (15, 19) contained therein so that they can be coupled to one another and moved in unison when the plunger is actuated. To provide such coupling the movable members (15, 19) have recesses and/or projections which cooperate to interlock the movable member of different block elements. One of the block elements, particularly the lighting element (11), may include a mechanism (16) for the high and low locking of the respective movable member (15), so that each switching element (10, 12) can be coupled selectively to it for operation either by touch engagement to provide a momentary switch or by locking engagement to provide a push-on, push-off switch.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
263 words
A control button unit, comprising: an actuating member which includes a housing for installation in a supporting wall, a plunger mounted on the housing for linear movement along a line, and spring means for urging the plunger in a predetermined direction along the line; a first block element having a broadside with an opening, the first block element additionally having a movable member with a projection which extends through the opening and perpendicular to the broadside of the first block element; a second block element having a broadside with an opening, the second block element additionally having a movable member with a recess; and a coupling member connected to the actuating member and having a plurality of receiving locations for selectively receiving block elements in parallel juxtaposition, the receiving locations being disposed so that the broadside of a block element in any receiving location is parallel to the line along which the plunger moves and so that the movable member thereof is displaceable in a direction parallel to the line along which the plunger moves, the first and second block elements being mounted on the coupling member at adjacent receiving locations, with the movable member of one of the first and second block elements projecting to a position for actuation by the plunger, wherein the projection on the movable member of the first block element extends through the opening in the broadside of the second block element and into the recess in the movable member of the second block element to couple the movable members of the first and second block elements together.
Claim 2
Dependent Claim
263 words
A control button unit, comprising: an actuating member which includes a housing for installation in a supporting wall, a plunger mounted on the housing for linear movement along a line, and spring means for urging the plunger in a predetermined direction along the line; a first block element having a broadside with an opening, the first block element additionally having a movable member with a projection which extends through the opening and perpendicular to the broadside of the first block element; a second block element having a broadside with an opening, the second block element additionally having a movable member with a recess; and a coupling member connected to the actuating member and having a plurality of receiving locations for selectively receiving block elements in parallel juxtaposition, the receiving locations being disposed so that the broadside of a block element in any receiving location is parallel to the line along which the plunger moves and so that the movable member thereof is displaceable in a direction parallel to the line along which the plunger moves, the first and second block elements being mounted on the coupling member at adjacent receiving locations, with the movable member of one of the first and second block elements projecting to a position for actuation by the plunger, wherein the projection on the movable member of the first block element extends through the opening in the broadside of the second block element and into the recess in the movable member of the second block element to couple the movable members of the first and second block elements together.
