Switch element supporting element and switch assembly for vehicular steering column combined switch

The invention provides a switch element supporting element and switch assembly for a vehicle steering column combined switch and an assembling method of the switch assembly. The switch element supporting element for the vehicle steering column combined switch comprises a main body; a channel opening which is located at the center of the main body and is used for receiving a slide element; two opposite slide ways which bulge from the two longitudinal side edges of the channel opening towards the center of the main body, thus enabling the slide element to slide along the slide ways in the channel opening after being assembled on the switch element supporting element; and slots which are located at corresponding locations on the two slide ways and are used for receiving the buckles of the slide element, thus assembling the slide element on the switch element supporting element. 本发明提供了种用于车辆转向柱组合开关上的开关元件支持件和开关组件及其组装方法。种用于车辆转向柱组合开关上的开关元件支持件，包括：主体；通道开口，位于所述主体的中心，用于接收滑动元件；相对的两条滑道，其从所述通道开口的两条纵向侧边处向主体的中心凸起，使得所述滑动元件在装配到
