According to the pilot, the airplane was in the initial takeoff climb from runway 32, when the engine lost power. He attempted a landing on a freeway median, but the airplane collided with a sign and fence posts. During an investigation, the instrument panel toggle switch, marked 'ignition,' would not stay in the up (on) position. Removal of the switch revealed that its plastic back casing was broken with no impact damage or deformation noted in the surrounding structure. The mechanic, who removed the switch, stated that it was installed excessively tight on the panel. After being removed from the panel, the switch would stay in the up (on) position. The engine was then successfully started and operationally checked.
Probable Cause: the pilot/builder's improper installation (overtorque) of the ignition switch on the instrument panel, which caused an internal switch failure and subsequent malfunction of the ignition system.
