The voltage of momentary contact push button switch is divided into two kinds, one is illuminated momentary push button switch, that is to say, there is LED inside the push button switch, it is customized according to the demand of the machine and equipment, for example, if the voltage is 12V, you have to use the 12V to control the machine, if you use 120 volt momentary push button switch to control the equipment, the light of the button will not light up.
Momentary push button switch to control the machine, if you use 120 volt momentary push button switch to control the equipment, the button light will not be lit up, the button can be customized to a variety of different voltages, which automation machinery and equipment are mostly used to 12 volt momentary push button switch, FILN company produced a 3V to 36V can be universal button switch, you just buy a button switch, whether 12v or 24V or 3V can be universal and the brightness is the same, usually 12v illuminated momentary push button switch LED is used to control the voltage, 3K resistor to control the voltage, then the button light will not light up.
Usually the LED of 12v illuminated momentary push button switch uses 3K resistor to control the voltage, so it will be very dark at 6V and bright at 24V, FILN button engineers added a chip design in the momentary push button led, the chip can control the voltage of the LED, and the light inside the button is the same when it’s from 3V to 36V.
The illuminated momentary push button switch can be produced in a variety of colors such as red, green, yellow, blue, white and so on, of which the red momentary push button is the most popular. If you need two or three colors, FILN can also customize the production.
