Abstract
Disclosed is a lamp switch for a parking brake and a structure of a lamp switch is configured to be changed, which indicates that a parking brake is pulled as lighting a lamp on a instrument panel of a vehicle by pulling a lever for the parking brake to prevent malfunction due to poor contact of the lamp switch when an external shock occurs, enhance fuel efficiency and reduce manufacturing cost due to weight reduction, and reduce the number of assembled fixtures.
Claims4
A lamp switch for a brake, comprising:
- a support member 110 in which at least one of a ground terminal 120 and a connection terminal 130 is provided with a single body by insert injection so as to implement the lamp switch for a parking brake in a contact state or non-contact state as power is applied or cut-off by being fixed to the parking brake via a fixation member, the ground terminal 120 including a ground part 121, and the connection terminal 130 including a connection part 131;
- a movable shaft 150 having a first end and a second end in which the first end is suspended on the support member 110 via a separation preventing member 140 through the support member 110 and the second end is provided to be movable in response to an operation of a parking brake lever L;
- a connection switch 160 formed to make the movable shaft 150 penetrate a center of the connection switch 160 to be positioned inside the support member 110 and provided so that both ends of the connection switch 160 are connected with the ground part 121 and the connection part 131;
- and
- a restoration spring 170 having a first end and a second end in which the first end of the restoration spring 170 is supported onto a bottom surface of the connection switch 160 and the second end of the restoration spring 170 is supported on the support member 110 to connect the connection switch 160 with the ground part 121 and the connection part 131 when the parking brake is actuated and provided to provide restoration force of the movable shaft 150 by making the movable shaft 150 penetrate a center of the restoration spring 170,
- wherein the support member 110 includes a fixation plate 111 having a fixation hole 111a, an upper guide plate 112 and a lower guide plate 113,
- wherein the upper guide plate 112 includes an upper surface and a bottom surface, and
- wherein the ground terminal 120 includes the ground part 121 provided in such a manner that a ground exposure plane 121a to and from which the connection switch 160 is connected and disconnected is formed on the bottom surface of the upper guide plate 112 formed on an upper end of the fixation plate 111 of the support member 110 by partially exposing a part of the bottom surface of the upper guide plate 112 by the insert injection and a ground fixation plate which is bent and extended from the ground part 121 in one direction to be integrally provided on the fixation plate 111 by the insert injection and a ground fixation hole which matches the fixation hole 111a is formed on the ground fixation plate.
