22mm Mini Voltmeter /Ammeter /Hertz Meter LED Digital Indicator Light

Principle of operation

The operating principle of 22mm Mini Voltmeter /Ammeter /Hertz Meter LED Digital Indicator Light is relatively simple. It contains one or more contacts that close when the pushbutton is pressed to energize the circuit; when the pushbutton is released, the contacts immediately open and the circuit is broken. This type of switch usually has a low operating force and a high speed of action, enabling it to respond quickly to operating commands.

AD16-22DS series led lamp is applicable to circuit with rated voltage 6V to 400V and frequency 50/60Hz for visual indication and signaling. The Color is: Red Yellow Blue Green,White .The indicator lamps signal any kind of electric installation including public, tertiary and industrial.

Types and Features

There are several types of momentary pushbutton switches, each with its own unique characteristics and applicable scenarios:

Normally open type (NO, Normally Open): when the button is not pressed, the contacts are in the disconnected state; when the button is pressed, the contacts are closed and the circuit is connected.

Normally Closed (NC, Normally Closed): When the button is not pressed, the contacts are closed; when the button is pressed, the contacts are closed and the circuit is broken.

Conversion type (Changeover): This type of switch has both normally open and normally closed contacts, which can be selected for use as required.

In addition, momentary pushbutton switches have the following characteristics:

Fast Response: Due to the fast action speed of the contacts, it is able to respond quickly to the operating instructions.

High reliability: Made of high-quality materials and advanced technology, momentary push button switch has a long service life and stable performance.

Easy to operate: the button is easy and convenient to operate, just a light press can realize the switching of the circuit.
