What is the push button switch?

The push button switch has a simple structure and is widely used in master control electrical appliances. In an electrical automatic control circuit, manually emit control signals to control contactors, relays, electromagnetic starters, etc.

The push button switch can complete the basic control of start, stop, positive and negative rotation, speed change, interlock and so on.

Usually, each push button switch has two pairs of contact, each pair of contact is made of a normally open contact and a normally closed contact. When the button is pressed, the two pairs of contacts act simultaneously, the normally closed contact is disconnected and the normally closed contact is closed.

Specify the function of each button to prevent mis-operation. The button cap is usually made in different colors in order to show the difference. It has red, green, black, yellow, blue, white and other colors. For example, red means stop button, green means start button and so on.

The following is a brief introduction to several button types:

Push button switches type Explain the meaning
1. Momentary push button switch Push button switches cause a temporary change in an electrical circuit only while the switch is physically pushed. A spring returns the switch to its original position immediately afterward.
2. Latching push button switch A latching push button function also referred to as maintained, means that it remains in a position until pressed again. It required to be pressed down or touched multiple times to either turn on or off the device or function.
3. Metal push button switch A metal button switch is a button made of metal. The shell of a metal button switch can generally be made of three materials: brass, stainless steel and zinc alloy.
4. Waterproof push button switch The waterproof push button switch is suitable for use in water splashing or outdoor environments. The waterproof button can avoid accidents.
5. LED push button switch The LED push button switch is a button with built-in LED lamp beads, which can light up the LED when the power is on. Now it can produce double color and tricolor button switches.
6. Car push button switch The car push button switch can engrave any symbol you want, and it can look more beautiful when installed on the car.
7. Emergency stop button switch The emergency stop button can also be called the “emergency stop button”, that is, when an emergency occurs, people can quickly press this button to achieve protection.
8. High current switch High current push button switches are more suitable for large-scale equipment. In order to enable the push button switches to withstand higher currents, all metal materials are made of red copper. Usually, the button current is 5A, while the high current push button switches can reach more than 10A.

The description of the momentary push button switch

The description of the latching push button switch

 

1. What is a latching push button switch?

Latching the push button switch means that install the switch on the panel of the push button, connect to the mechanical equipment then connect the power supply, press the latch push button switch, its lamp will light up, the machine starts. When your hand presses latch on off push button switch, its lamp is off, the machine stopped.

2. What’s the difference between a momentary pushbutton switch and a latching switch?

The biggest difference between the momentary push button switch and the latching push button switch is that the latching switch has a locking pin and a spring plate inside.

The working principle of momentary push button switch:

As shown in Figure ①, manually press the button, the moving contact of the button will be connected when it moves down to the static point, and when the hand is released, the moving contact will move up under the action of the spring and resume disconnection (normally open button, the only press can be connected, otherwise it will always be disconnected);

As shown in the figure ②, manually press the button, the moving contact of the normally closed button moves down, and the moving contact is disconnected from the static contact. When the hand is released, the moving contact moves up under the action of the spring and resumes connection (normally closed Close button, it can be disconnected only by pressing it, otherwise it will be connected all the time).

 

Working principle of latching push button switch:

As shown in Figures ④ to ⑤, the latching push button switch has a locking function. After pressing and releasing, the button can be fixed in position under the action of the locking pin.

At this time, the moving contact of the button moves down to the static contact, which can be kept in place. The circuit is always energized, and the lock pin can be unlocked after pressing and releasing it again, and the moving contact and the static contact are disconnected so that the circuit is disconnected.

Where are the pushbutton switches used?

 

Metal push button switches are widely used, and there are many products covered.

If a device needs a mechanism to control its operation and stop, then the button switch is undoubtedly one of the best choices, and secondly, you can also choose the rocker switch.

The most commonly used equipment includes kitchen equipment such as coffee machines, testing equipment, public equipment, etc.

The current pushbutton switch is not limited to only the function of controlling current. If you add a green LED indicator inside, then this switch button can emit light when energized; if you add two colors of LED indicators inside, then This is a double color pushbutton switch that can indicate two kinds of equipment; if you need waterproof push button switch, glue on the tail can reach the IP67 waterproof level, and the surface symbol engraving is even easier.

Can a push button switch act as a push button start switch for a device?

Pushbutton switches can be used as push button starter switches, because their principles are the same, and they all work by controlling the opening and closing of the circuit.
