The mechanism has a body (1) covered with a lid (4). A switchover unit (5) is placed on the lid and transmits force exerted by a user on an outer button (3) to contacts disposed inside the body. The body has lateral hooks (6) that anchor the body to inner walls of a cavity in which the mechanism is installed. The hooks are provided with a screw (7) for activation of the hooks and lateral locking rings (8). |
