first of all to find the appropriate installation site, you need to ensure that the surrounding environment is not corrosive gas, do not put in the area prone to fire or dust, but also to ensure that the voltage is stable, otherwise too large will make the ballast broken, and the light bulb connected to the wire can not be arbitrary growth
Button switch refers to a switch that uses a button to push the transmission mechanism to make the moving contact and the static contact press on or off and realize circuit switching. The star connection method of phase power is to connect one end of each phase power supply or load to one point, and the other end of them is used as a lead wire, which are three phase wires of three-phase power.
In general, LEDs operate at a voltage of 2-3.6 V. Only a weak current is needed to emit light properly. Whereas with ordinary incandescent lamps, the power of the bulb is about 40 watts, and kW/h is one degree of electricity, if used continuously for 10 hours, that is about 0.4 degrees of electricity.
Push button switche and toggle switches are both miniature switches with a very simple structure. In addition to some differences in appearance and structure, there are differences in the working principle and applications. The following is an introduction to the differences between push-button switches and toggle switches.
One, when using the lamps and lanterns try not to switch frequently, although the number of times the LED lamp is resistant to switching is about 18 times that of ordinary fluorescent lamps, but too frequently will still affect the life of the internal electronic components of the LED lamp, thus affecting the life of the lamps and lanterns.
Protective buttons, which have a protective appearance, some are dynamic break type or dynamic close type, there is also a dynamic close and dynamic break button. With a signal light, which can give instructions, some are called action click buttons.
Push Button switch some from the color of the terminals can go to distinguish, this is to avoid operating errors, - generally will be made of different colors button cap, green (or blue) for normally open contacts, red (or pink) is normally closed contacts.
led lights are extremely common lamps in modern life, led lights in the use of the process may not appear bright or have low light and other situations, why is this? Today by PChouse for you to answer one by one.
push button switch structure: consists of button cap, reset spring, fixed contact, movable contact housing and pillar linkage, etc. The main categories are as follows
There are many types of switches, for example, there is a push button switch, this switch is normally open long closed how to distinguish?
1. LED lights flicker frequently may be due to the failure of the driving power supply. For example, the driver power supply is too large, the lamp beads can not withstand the high power supply, so it will flicker. You can remove the LED light, open the housing, and then replace the LED driver power supply.
Emergency stop button can also be called "emergency stop push button switch", the industry referred to as the emergency stop button. As the name implies, the emergency stop button is when an emergency occurs, people can quickly press this button to achieve protective measures.
Float switch structure is very simple, the use is also very convenient level control device, it does not need to provide any power, no complex circuit, than other mechanical open light volume will be much smaller, life is also very long, so has so many advantages, is also the reason people are willing to choose it.
Protective button: A button with a protective housing that prevents the internal button parts from mechanical damage or human contact with the electrically charged parts, and its code is H.
An emergency stop switch, also known as an emergency stop switch, emergency stop switch, emergency switch, termination switch or emergency button, emergency stop push button switch, is a fail-safe control switch that provides safety for machinery and equipment. people who use the machine.
Speaking of button (button) switch, I believe that many people will not feel unfamiliar, almost every day will encounter a variety of button switches.
Buttons installed on the panel should be arranged neatly and reasonably, for example, from top to bottom or from left to right according to the sequence of motor start. Adjacent
A comfortable home, certainly not without a good lamp, at present there are many in the selection of lamps and lanterns tend to ask whether they can save energy and environmental protection, so most people will choose the LED lamp, it is a more popular by people a lamp.
Switches and sockets are common building materials in our homes, bringing convenience to our daily use of electricity. However, there are many considerations when wiring switches and sockets, otherwise not only the lights can not light, but also cause a short circuit.
There are many kinds of push button switch structures, which can be divided into common snap type, mushroom head type, self-locking type, self-resetting type, rotary handle type, type with indicator light, type with light signal and key type, etc.
