Abstract
A subassembly having a main housing and an electric switch arranged within the main housing. The main housing has a wall provided with an opening and the switch has a switch housing and an actuating element. The switch is arranged within the main housing such that the actuating element projects through the opening in the wall so as to extend exteriorly of the main housing and thus be actuatable from the exterior of the main housing. The wall has a first contact surface in the region of the opening and the switch housing has a second contact surface in the region of and surrounding the actuating element. The two contact surfaces are in pressure contact with each other when the switch is installed in the main housing with the actuating element of the switch projecting through the opening, thereby eliminating the need for an additional seal between the contact surfaces of the main housing and the switch housing. The subassembly can be used, for example, in a steering wheel lock, an ignition lock, a door lock or the like in a motor vehicle, or it can be used in domestic appliances or in machine tools.
