Abstract

The utility model relates to a function-changed switch for electric equipment which belongs to the improvement of the switch for the electric equipment, and comprises box type wire holders with unified specification and structure, switch bases, double-sockets, three-sockets and corresponding box covers which are mutually matched. The switch can be used separately and assembled and installed, and the switch can change the functions. For example, the switch is changed into a socket, or the socket is changed into the switch. Some switch or socket is in failure or is damaged in use, the utility model can be repaired or replaces the parts at any time. Simultaneously, each switch base or socket is provided with a guard plate 7. The utility model has no electric shock hazard and is very safe in repairing and replacing the parts or changing the functions.

Description

Functiona-changed switch for electric equipment

The utility model is the supporting formula appliance switch of a kind of function-variable, belongs to the appliance switch technical field in the electricity.

Existing single switch or socket, the needs that not exclusively adapt to each consumer electronics development, and present more unit switch, because structural design is unreasonable, two shortcomings of ubiquity, the one, switch in the unit switch or socket, function can not change, the 2nd, in use, if one of them switch or socket damage, can not single replacing or repairing.

For overcoming the prior art weak point, the utility model provides a kind of and can singlely use, the supporting formula appliance switch of installation capable of being combined, convertible function.

The utility model is to realize like this, it comprises by switch base, double socket, three sockets, junction block and connector are formed, switch base, the seat board shape specification of double socket and three sockets is identical, be provided with the unified fastener hole in safe plate washer and position, junction block be specification framework unified be provided with the fuse bridge chair can be respectively and switch base, the boxlike junction block that double socket and three sockets match, four limits, box body bottom have wire hole, one side in the box body is provided with fuse bridge chair and the wiring part that is connected with it, another side is provided with the wiring part, lid has and switch, the hole that double socket or three sockets adapt is equipped with the fuse that matches with fuse bridge chair in the boxlike junction block and inserts bridge in the lid.

Make description of drawings below:
