A base seat 12 is disposed on the other side (bottom portion) of the receiving space 11. The base seat 12 has multiple contact legs 121 outward protruding from the case seat 1. A linking member 13 is disposed on a lateral side of the base seat 12 for controlling the respective contact legs 121 to form different conducting states.

[0037] In a preferred embodiment, a securing section 14, (which can be an outer thread), is disposed on an outer circumference of the case seat 1. In cooperation with an auxiliary member (such as a nut, not shown), the case seat 1 can be secured onto a preset panel by means of the securing section 14. A recessed hollow section 122 is disposed on one side of the base seat 12 (at the center thereof) in adjacency to the receiving space 11. The hollow section 122 serves to receive a light-emitting member 16 therein. An elastic member 132 and a locking member 15 are disposed between the linking member 13 and the case seat 1. The elastic member 132 applies an elastic force to the linking member 13 to make the linking member 13 restore to its home (not operated) position. The locking member 15 serves to keep the linking member 13 in an operated or not operated position in a specific state. (For example, when the linking member 13 is forcedly operated once, the linking member 13 is retained in the operated position, while when the linking member 13 is forcedly operated again, the linking member 13 is restored to the not operated position). A connected section 133, (which can be a raised block), is disposed on an outer surface of the linking member 13.

[0038] The support seat 2 is received in the receiving space 11. A penetrating hole 21 is formed through a center of the support seat 2. An inner annular shoulder section 211 is formed on a middle portion of an inner circumference of the penetrating hole 21. A connection section 24 and a connected section 22 are disposed on an outer side of the support seat 2. The connection section 24 serves to connect with the connected section 133. In a preferred embodiment, an outer flange 23 is disposed on an outer circumference of the support seat 2. An annular groove 231 is further disposed on the outer circumference of the support seat 2 above the outer flange 23. The connection section 24 has a connection guide split 241 for fitting on and holding the connected section 133 (raised block), whereby the support seat 2 is securely connected with the linking member 13.

[0039] In this embodiment, the connected section 22 has at least one L-shaped locating guide channel 222 disposed on the outer circumference of the support seat 2. One side of the locating guide channel 222 is transversely disposed on the outer circumference of the support seat 2.

In addition, an abutment flange 311 is annularly disposed on an outer circumference of the hub section 312.

[0041] In a preferred embodiment, the cap assembly 3 further has a sealing washer 32 disposed on the inner annular shoulder section 211 of the penetrating hole 21. When the hub section 312 is plugged into the penetrating hole 21, the abutment flange 311 presses the sealing washer 32 to achieve sealing and locating effect.

[0042] The pushbutton 4 is disposed in the opening of the receiving space 11. A fitting section 43 is disposed under a bottom section of the pushbutton 4 for fitting onto the cap plug 31. In addition, a connection section 42 is disposed under the bottom section of the pushbutton 4 for connecting with the connected section 22, whereby the pushbutton 4 can be connected with the support seat 2 to drive the support seat 2 to drive the linking member 13 to operate. In a preferred embodiment, a mark cover 41 with a character, a figure or a symbol is inlaid in a surface of the pushbutton 4, which surface is distal from the support seat 2. Moreover, the pushbutton 4 is made of a transparent material.

[0043] In this embodiment, the connection section 42 has at least one hook section 422 disposed on an inner circumference of the pushbutton 4 corresponding to the locating guide channel 222. In addition, a raised stopped section 421 is disposed on the hook section 422. When assembled, the hook section 422 of the pushbutton 4 extends from the cut 2221 into one side of the locating guide channel 222. Then, the pushbutton 4 is rotated to make the stopped section 421 of the hook section 422 transversely moved through the stop section 221 and inserted into the other side of the locating guide channel 222. After the stopped section 421 passes through the stop section 221, the stopped section 421 is restricted from moving, whereby the pushbutton 4 and the support seat 2 are securely assembled with each other without easy loosing and detachment. In the case that it is necessary to detach the pushbutton 4, a proper force is applied to the pushbutton 4 to make the pushbutton 4 rotate in a reverse direction relative to the support seat 2. Under such circumstance, the stopped section 421 can pass through the stop section 221 in a reverse direction, permitting the pushbutton 4 to be taken off from the support seat 2.
