Now in conjunction with the accompanying drawings switch one preferred embodiment that the utlity model has Presentation Function is further described.

Fig. 1 is the sectional side view of existing switch.

Fig. 2 is the three-dimensional exploded view of the utility model preferred embodiment.

Fig. 3 is in the sectional side view of opening for indicator light in the utility model preferred embodiment.

Fig. 4 is in the sectional side view of closed condition for indicator light in the utility model preferred embodiment.

See also the three-dimensional exploded view of the represented the utility model preferred embodiment of Fig. 2.The loam cake 11, lower cover 12, the fixed iron piece 13 that comprise a housing among the figure, the button 21 of one switching device shifter, Access Division 211, spring 22, shell fragment 23, supporting slice 231, contact terminal 232, common terminal 24, raised line 241, contact terminal 25, contact terminal 251, neon lamp guide wire, resistance 33, circuit board 34, lampshade 35 that the neon lamp 31 of one display unit, a flexible member 321 and a buffer unit 322 constitute, clamp iron plate 41, clamp pushing block 42.

The switch that the utlity model has Presentation Function is to assemble clamp pushing block 42, clamp iron plate 41, common terminal 24, contact terminal 25 in regular turn and shell fragment 23 is positioned on this raised line 241 in this lower cover 12; And the button 21 that will be embedded with lampshade 35 by the Access Division 211 with these loam cake 11 clampings; The circuit board 34 that will be welded with neon lamp 31, neon lamp guide wire and resistance 33 again is installed in this button 21 belows, and a hole and this button 21 that spring 22 is passed on the circuit board 34 are affixed, loam cake 11 after will making up again engages with lower cover 12, the other end of spring 22 is positioned on this supporting slice 231, be that available fixed iron piece 13 is fixed/lower cover, be assembled into a switch, wherein, when switching this switch, this contact terminal 232 is to open light fixture in order to contact with this contact terminal 251.

This neon lamp guide wire that is characterised in that of the present utility model is used in combination a flexible member 321 and a buffer unit 322, and wherein this flexible member 321 can be made with an electric conducting material is one-body molded with this buffer unit 322.Use the copper cash of straight line bending to contact with contact terminal 25 in the utility model preferred embodiment as a flexible member 321, relend by the one-body molded spiral type copper cash spring of making as buffer unit 322, so can relax the pressure that is born when the neon lamp guide wire is long-term to be contacted with contact terminal 25, has not yielding, the fracture of lead, and the scolding tin effect that is difficult for dropping, can prolong display unit normal useful life, thereby obtain the switch with Presentation Function of high value.
