Abstract
An actuation device () for an explosion-proof housing () in compliance with the ignition protection category 'pressure-proof encapsulation'. The actuation device () has an actuation unit () with a manually actuatable actuation element (), and an actuation device () having a switch unit () with a switch element () for switching an associated electrical contact. The actuation unit () is located outside the housing (), whereas the switch unit () is located in the interior space () of the housing (). An adapter device () mechanically connects the actuation unit () and the switch unit () and comprises at least one adapter plunger () that is supported so as to be movable in axial direction (A) in order to transmit the movement of the actuation element () via the adapter plunger () to the switch element (). The adapter plunger () is arranged in an adapter channel () so as to be axially shiftable while forming a gap () that is resistant to ignition transmission.
