Electromagnetic instant-touch type power supply switch

Abstract

The invention relates to a electromagnetic instant touch type power switch which is used for controlling the power supply of an electrical appliance by matching with a remote controller of the electrical appliance or a network, and comprises a switch unit, a key driving unit, a connecting piece, and a circuit module providing electric drive for the key driving unit; the switch unit is a key switch with key locking function; the key driving unit is an electromagnet including a drive coil and a movable iron core, one end of the drive coil is connected to a commercial power input second terminal, the other end is connected to the circuit module; the two ends of the connecting piece are respectively connected with the movable iron core and the key of the key switch; the circuit module includes a singlechip and an electromagnetic switch connected to the singlechip, one end of the electromagnetic switch is connected to the drive coil, while the other end is connected to a commercial power input first terminal. By adopting the electromagnetic instant touch type power switch of the invention, only once instant energization is needed to reach the aim of the on / off of the power supply, continuous power supply is not needed any more, and the effect of energy-saving can be actually achieved.

Description

Technical field [0001] The invention involves a power switch, especially an electromagnetic instantaneous tactile switch. Background technique [0002] With the increasing level of living standards, the requirements for the intelligence of electrical appliances are getting higher and higher, so remote control electrical equipment has entered all areas of people's production and life; when used, remote control equipment in the remote control machine controls the machine, Make the machine work, convenient and fast; but when these electrical equipment is not used, they have been standing away. Some components in the machine are still working and cannot be completely cut off.There are certain safety hazards. [0003] According to the test, the standby energy consumption of most of the home appliances is above 3 watts.As early as 2001, the United States had issued a presidential order, asking the federal government to purchase products as much as possible to purchase products with a s...

Problems solved by technology

Therefore, scientists from all over the world are working hard on how to reduce the standby power consumption of home appliances; at present, including domestically, many companies have developed related electronic products for standby energy saving, all of which only reduce power consumption on electronic circuits. , but cannot completely cut off the power supply to achieve a true "zero power consumption" standby effect; although they claim in publicity that they can also use traditional "relays" to cut off the power supply, this is just a "false energy saving". The above is that it consumes more power, because: the traditional "relay" needs its coil to be continuously energized to generate magnetic force and attract the switch shrapnel to achieve the function of "turning on" the power supply. The increased power consumption after the power supply is "turned on" (about 70-100 milliamps), which is dozens of times higher than the required power consumption (about 4-10 milliamperes) in standby mode. Therefore, although the standby power consumption is apparently saved, it greatly increases the use of When the power consumption is high, there is no real energy-saving effect
