In a state wherein front ends of latch membersA andB are apart from each other so that the upper surface of an alignment plate/positioning memberis outside, a pressing sectionPU of a heat sink memberis brought into contact with the periphery of a semiconductor device

Semiconductor device socket

In a vehicular lever switch having a resistor at a fixed contact plate to be combined with a pivoting knob, when a passenger charged with static electricity touches the lever, the resistor is to be prevented from being damaged. A fixed contact plate is arranged with a resistor and conductors and extended from both ends thereof in a ring-like shape to constitute a fixed contact. Further, an extended portion extended in a circular arc shape is formed on an outer side of the resistor with a gap from the conductor. Even when the hand of a passenger charged with static electricity touches a vicinity of a pivoting knob and the static electricity is applied to the fixed contact plate, the static electricity flows to the extended portion and is discharged via the conductor and a terminal. Thereby, the resistor is not damaged by static electricity. Further, it is not necessary to ensure a distance from an end edge of the pivoting knob to the fixed contact plate to be long in order to avoid propagation of static electricity and therefore, a degree of freedom of a shape of the lever can be enhanced.

An automobile knob switch assembly comprising an operating lever 1 that has a shaft rod 1a. A terminal plate 2 is inserted into an opening part if of the operating lever 1. A movable plate 3 has a movable contact plate 13 that contacts the stationary contact plates 8 placed in the terminal plate 2, a through hole 3a through which a cylinder part 4a of a moderator 4 is inserted, and latching pieces 3b that are latched onto the moderator 4. The moderator 4 has an elastic claw 4c that is latched onto the shaft rod 1a. A knob 5 has a latching part 5b that is engaged to a latching piece 3e formed in the periphery of the movable plate 3. A second embodiment is disclosed that has two knobs for the rotary switch installed at the tip of the operating lever 15. The construction of the knob switch assembly permits the parts of the switch assembly to be automatically assembled with machines for mass production and reduced costs.
