A control device for pressurized fluids according to claim 1, wherein said at least one female contact extends from said mount through said at least one through-hole in said plate such that a distal end of said at least one female contact projects outwardly from said at least one through-hole in said plate on a side of said plate facing away from said mount. 3. A control device for pressurized fluids according to claim 1, wherein said at least one through-hole in said mount includes a funnel-shaped portion opening toward said at least one male contact for guiding said at least one male contact into said at least one through-hole in said mount. 4. A control device for pressurized fluids according to claim 3, wherein the cross-sectional size of said funnel-shaped portion at its narrowest point is at most equal to the cross-sectional size of a proximal end of said at least one female component. 5. A control device for pressurized fluids according to claim 1, further comprising at least one spring element disposed in said at least one female contact oriented in the direction of the longitudinal axis of said at least one female contact and convex toward an imaginary centerline of said at least one female contact. 6. A control device for pressurized fluids according to claim 1, wherein said mount for said at least one female contact is detachably joined to said plate by a fastener. 7. A control device for pressurized fluids according to claim 1, wherein said plate is designed as a printed circuit board. 8. A control device for pressurized fluids according to claim 1, wherein said first electric device includes at least one electromagnet. 9. A control device for pressurized fluids comprising first and second housing components adapted to be removably coupled together, a first electric device in said first housing component, a second electric device in said second housing component, a valve mechanism in said first housing component in communication with said first electric device, said valve mechanism being controlled by said second electric device, said second electric device including a plate and at least one female electrical contact, said first electric device including at least one male electrical contact disposed opposite said at least one female contact, said at least one female contact and said at least one male contact forming an electric connection when said first and second housing components are joined together, a mount for said at least one female contact having at least one through-hole for receiving said at least one female contact, said mount being supported by said plate on a side facing said at least one male contact such that said at least one through-hole in said mount is oriented substantially coaxially with at least one through-hole in said plate, said at least one female contact being disposed in said at least one through-hole in said mount such that it extends into said at least one through-hole in said plate, said at least one through-hole in said mount including a funnel-shaped portion opening toward said at least one male contact for guiding said at least one male contact into said at least one through-hole in said mount, said mount including first and second mount components connectable along a line transverse to the longitudinal axis of said at least one female contact, said first mount component being positioned below said second mount component, said at least one through-hole in said mount including a first portion disposed in said second mount component and a second portion disposed in said first
