SWITCH DEVICE OF BACK-UP LAMP

摘要

PURPOSE: A switch device of a back-up lamp is provided to improve a contact structure of switch by stably fixing positions of a contact terminal and a fixing terminal and to secure the stability of a contact structure without flowing oil from an inside of a transmission. CONSTITUTION: A push rod(60) is entered inside a switch housing(51) when a driver does not gear a backward gear. A contact terminal(70) is contacted with an inside of a switch body(55) by separating from a fixing terminal(75). A back-up lamp is not lighted because a back-up light switch is turned off. The push rod(60) is moved inward a transmission by the elasticity of a return spring(65) when the driver shifts the backward gear. The contact terminal(70) is contacted with the fixing terminal(75) by sliding in the inside of the switch body(55). The back-up lamp is lighted by turning on the back-up lamp switch. Thereby, the stability of a switch contact structure is secured. An inflow of oil into a switch housing(51) is prevented by installing a packing member(80) between the push rod(60) and a rod combining portion(61).
