Abstract
A switching device for controlling a large amount of current includes a circuit board carrying electronic components thereon, a power-switching element electrically connected to the circuit board, and a housing disposed underneath the circuit board and containing the power-switching element therein. The housing made of a heat-conductive material includes a heat-sink block having a sloped surface on which the power-switching element is mounted. Connecting leads extending from the power-switching element are positioned at an upper portion of the sloped surface which is close to the circuit board. In this manner, the length of connecting leads is shortened and heat and noises generated therein are suppressed.
