Fig. 6 is a sectional perspective view of the switch device 1 shown in fig. 2a taken along lines S1-S1, and fig. 7 is a sectional perspective view of the switch device 1 shown in fig. 2a taken along lines S2-S2. As can be seen from fig. 6 and 7, the contact portion 424 can contact the tact portion 331 of the tact switch 330. The tact portion 331 is located on the upper side of the tact switch 330. Contact portion 424 may be supported by 1

st pillar portion

421, 2 nd pillar portion 422, and 3 rd pillar portion 423. The 3 rd pillar portion 423 may be disposed perpendicular to the 1 st pillar portion 421 and the 2 nd pillar portion 422. The 1 st, 2 nd and 3

rd pillar portions

421, 422 and 423 have a substantially T-shape.

The push rod 40 may move in a downward direction together with the button 50, thereby pressing the tact portion 331 downward through the contact portion 424. If the tact portion 331 is pressed, the light source 310 is activated, so that a signal for turning on the vehicle emergency lamp can be transmitted to the BCM of the vehicle through the circuit terminal 320. The tact switch 330 is configured to obtain an elastic force to ensure that the tact portion 331 can move upward again when pushed downward and moved downward. The tact switch 330 includes an elastic member (not shown) that applies the elastic force to the tact portion 331. The elastic member may be provided in one of a variety of well-known ways to provide elastic force. For example: the elastic member may be a member of various types such as a compression spring, an extension spring, a torsion spring, and a gas spring, or may be a member formed of a material such as rubber and elastically compressed.

In one embodiment, the elastic member includes: a funnel-shaped portion made of a rubber material and expanding downward; a convex portion protruding upward from the funnel-shaped portion. The elastic member is configured such that the funnel-shaped portion is elastically deformed in a process of pressing the convex portion downward. By pressing the projection portion downward and moving it downward, a switch (switch) inside the tact switch 330 can be pressed. The tact portion 331 may be disposed on an upper side of the elastic member. The switch inside the tact switch 330 may be disposed at a lower side of the elastic member.

The 3 rd projection 240 provided at the longitudinal sidewall 210b of the jacket 20 may pass through the opening 531 formed at the 1 st combining wall 530. The 4 th protrusion 440 formed on the 2 nd sidewall 410b of the push lever 40 may pass through the opening 541 formed on the 2 nd coupling wall 540 of the push button 50.

The length of the opening 541 formed in the up-down direction is longer than the length of the 3 rd projection 240 formed in the length direction. In the opening 541, the 3 rd projection 240 may perform a relative movement in an up and down direction. The vertical range in which the push button 50 and the push rod 40 can slide is limited by the vertical length range of the opening 541.

Referring to fig. 7, the 1 st sidewall 410a of the push rod 40 and the lateral sidewall 210a of the sleeve 20 may be disposed parallel to each other. The support portion 110 is fixed to the sleeve 20. The protrusions 111 formed on the sidewalls of the support part 110 may pass through the openings 220 formed on the lateral sidewalls 210a of the sleeve 20.

Fig. 8 is a front view illustrating a method of controlling a lamp of a vehicle by the switching device 1. Activation of the vehicle's emergency light may be turned on by tapping switch 330. Referring to fig. 8, if the user presses the upper wall 510 of the button 50 with a certain force, the button 50 moves downward, and the contact part 424 presses the tact part 331 downward, so that the emergency lamp can be turned on.

In the state where the emergency lamp is turned on, the emergency lamp continuously blinks as long as there is no other input. In the state where the emergency lamp is turned on, the light source 310 of the circuit assembly 30 is turned on, and the user can recognize this. Then, if the user presses the upper wall 510 of the button 50 again with a certain amount of force, the emergency light is turned off (turn off). In a state where the emergency lamp is turned off by the push input of the user, the light source 310 of the assembly 30 is turned off, and the user can recognize the turn-off of the emergency lamp.

Fig. 9 is a schematic view showing a path range in which light generated by the light source 310 is irradiated to the light irradiation region T of the button 50. Fig. 9(a) is a front view of the push button 50 as viewed from above, fig. 9(b) is a sectional view of the switch device 1 taken along the line S1-S1 shown in fig. 2a, and fig. 9(c) is a sectional view of the switch device 1 taken along the line S2-S2 shown in fig. 2 a.

Referring to fig. 9(b), the pushrod 40 forms an empty space in which no light-blocking obstacle exists within an angle range Ax connecting the light source 310 and the upper end of the 2 nd sidewall 410b in a cross section parallel to the lateral direction (X-axis direction) and the longitudinal direction (Z-axis direction). The pushing portion 420 may be arranged outside the angular range Ax. An angle A1 formed by one side edge of the angle range Ax and the horizontal line is 70-80 DEG, and an angle A2 formed by the other side edge of the angle range Ax and the horizontal line is 70-80 deg. For example: one side edge of the angular range Ax forms an angle a1 of about 71 ° with the horizontal and the other side edge of the angular range Ax forms an angle a2 of about 77 ° with the horizontal.

Referring to fig. 9 c, the pushrod 40 forms an empty space in which no light-blocking obstacle is present within an angular range Ay connecting the light source 310 and the upper ends of the 21 st sidewalls 410a in a cross section parallel to the longitudinal direction (Y-axis direction) and the vertical direction (Z-axis direction). The pushing part 420 may be disposed outside the angular range Ay. An angle A3 formed by one side edge of the angle range Ay and the horizontal line is 70-80 degrees, and an angle A4 formed by the other side edge of the angle range Ay and the horizontal line is 70-80 degrees. For example: one side edge of the angular range Ay forms an angle A3 with the horizontal and the other side edge of the angular range Ay forms an angle a4 with the horizontal of about 76 °.

As can be seen from fig. 9(a), the light from the light source 310 is emitted into the angular ranges Ax and Ay and is irradiated to the light irradiation region T of the push button 50. At least a part of the light can be radiated to the outside through the light irradiation region T.
