Embodiment Construction

[0030] figure 1 An exploded view of the control element 1 comprising a mounting unit 2 with a panel 3 and a holding element 4 is shown according to the invention. The control element 1 can be embodied as a button 5, in particular a double button. The control element 1 preferably has a two-part housing comprising a socket 6 and a front ring 7 plugged onto the socket. The socket 6 has a cylindrical body, embodied as the lower part of the housing. The front ring 7 serving as the upper part of the housing of the control element 1 is preferably designed as a superelliptical shape, thus a hybrid of an ellipse and a rectangle. The front ring 7 has a bearing surface 8 arranged on its underside, which protrudes on the left and right sides beyond the socket 6 arranged centrally below the front ring 7 . At least one button 5 is provided in the front ring 7 . At least one engaging element 9 is provided on the socket 6 . The snap-in element 9 is preferably designed as a wing, with two...

Abstract

The invention relates to control element (1) comprising an installation unit (2) which has a front plate (3) and a holding element (4). The control element (1) is characterized by at least one locking element (9) which can be introduced into the holding element (4) through an opening (15) in the front plate (3) so as to lock.

Description

technical field [0001] The invention relates to a control element comprising a mounting unit with a faceplate and a holding element. Background technique [0002] This type of installation unit is used on machines or electrical equipment controlled by command control devices (such as buttons, selector switches and other command control devices that act on the control device). These control devices are mounted on switchboards, operator panels, switch cabinet doors or enclosure covers. Control devices are generally of modular construction; that is, they consist of an actuator, a fastening part (eg ring nut or mounting clamp) and one or more switching elements embodied as normally closed or normally open switching elements. During installation, the actuator is generally inserted into the hole on the switchboard from the front, and then fixed with fixing parts from the back. The switching element is mechanically connected to the actuator or fixed part with elements such as scr...
