Abstract
The invention aims to provide a voltage change-over switch which can convert 220V alternating current into safe direct current and can be controlled by a switch.
Description
Technical Field
The invention relates to home decoration equipment, in particular to a voltage conversion switch which converts alternating current into direct current and is integrated with a switch.
Background
At present, a lighting switch as a necessary product of home decoration enters thousands of households, the living quality is continuously provided by people, the household alternating current can not meet the requirement far away, and other external equipment is required to meet the requirement, so that the attractiveness of the whole house is influenced.
Disclosure of Invention
The invention aims to provide a voltage conversion switch which converts 220V alternating current into safe direct current and can be controlled by a switch.
The technical scheme of the invention is as follows: the key point of the voltage conversion switch is that a circuit board is arranged on the back surface of the switch, and a voltage conversion electronic circuit is arranged on the circuit board.
The invention has the beneficial effects that: the voltage conversion switch of the invention converts alternating voltage into direct voltage for household direct current equipment.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further described with reference to the accompanying drawings in which:
as shown in fig. 1, a voltage transfer switch is provided, which is characterized in that a circuit board (1) is arranged on the back of the switch, a voltage transfer electronic circuit (4) is arranged on the circuit board (1), two contacts (2) are arranged on the circuit board (1), the contacts (2) are connected with the transfer electronic circuit (4), a switch sheet (3) is arranged on the contacts (2), the switch sheet (3) is connected with a power supply, the switch sheet (3) is respectively connected with the two contacts (2) to form reverse voltage, and the forward and reverse rotation of a motor is generally controlled in practical use; if a small-sized direct current motor is arranged on the roof, the motor is connected with a disc, an electric wire is wound on the disc, one end of the electric wire is fixed on the disc, the end of the leaked wire is connected with the circuit board, and the other end of the electric wire is connected with an upper lamp; the small-sized direct current motor is fixed on a roof, when the motor works when being electrified, the motor rotates forwards and backwards to drive the wire coil to be wound and unwound, and because one end of the wire is connected with the lamp, the wire coil is wound and unwound to drive the lamp to be wound and unwound, so that the lamp is convenient to replace.
Claims (1)
1. The key of the voltage conversion switch is that a circuit board (1) is arranged on the back surface of the switch, a voltage conversion electronic circuit (4) is arranged on the circuit board (1), and two contacts (2) are arranged on the circuit board (1).
