FAQ

1. How does a push button switch work?

Push button switch is a small switching device used to close or disconnect control circuits to issue instructions or program control. It consists of an actuator, a main body and a contact point.

Contacts are divided into constant open contacts and constant closed contacts. When you press the actuator, the spring moves, the contact opens or closes, and it completes the current loop or circuit break.

The main body of the switch is made of non-conductive plastic, the actuator is made of metal or plastic, and the contacts are made of copper. In order to keep good electrical conductivity at lower voltage and small current, a layer of gold or silver will be coated on the surface of copper contacts.


2. What are the types of switches?

Push buttons are classified into maintained push buttons and momentary push buttons according to the reset mode of operation mechanism.  It is also classified into plastic push button and metal push button according to the main body material.


3. What is momentary push button switch?

A type of switch usually in the form of a push button, that can’t be latched the operation mechanism in its set position. Momentary switches may be normally open or normally closed. A normally open switch doesn’t make contacts contact until and unless it is held down. A normally closed switch is always making contacts contact until the button is pushed.


4. What is maintained push button switch?

A type of switch usually in the form of a push button, that can be latched the operation mechanism in its set position when you press the operation mechanism. Maintained switches may be normally open or normally closed. A normally open switch doesn’t make contacts contact until and unless it is held down.


5. What are the 4 types of switches?

In the electrical control circuit, common four types of switches are SPST, SPDT, DPST and DPDT switch.


6. What is SPST switch?

SPST means a Single Pole Single Throw switch is a switch that only has a single input and can connect only to one output. This also means it only has one input terminal and only one output terminal. A Single Pole Single Throw switch serves in circuits as on-off switches. When the switch is closed, the circuit is on. The two terminals are either connected together or disconnected from each other. For example, a light switch.

Another common switch-type is the SPDT. SPDT have one common pin and two pins which vie for connection to the common. SPDT are very great for selecting between two power sources, swapping inputs, or whatever it is you do with two circuits trying to go one place. Most simple slide switches are of the SPDT variety. Actually SPDT can be made into an SPST by just leaving one of the switch terminals unconnected


7. What is the difference between SPST and DPDT switch?

DPDT switch is basically two SPDT switches, which can control two separate circuits, but are always switched together by a single actuator.


8. What is the difference between SPST, SPDT, DPST and DPDT switch?

SPST is a basic on/off switch that can turn a single electrical circuit on or off. A SPST switch has one input terminal and one output terminal.

A SPDT switch one input circuit to one of two output circuits. The type of switch is sometimes called an A/B switch because it lets you choose between two output circuits, called A and B. A SPDT switch has one input terminals and two output terminals that is A and B outputs.

A DPST switch turns on or turns off two circuits. A DPST switch has two inputs terminals and two outputs terminals. The on/off state of the two circuits is controlled synchronously.

A DPDT switch can control two separate electrical circuits, connecting each of two inputs to one of two outputs. So a DPDT switch has six terminals, include two inputs, two A outputs and two B outputs.


9. What does a double pole switch do?

A double-poles switch is mechanically operated by the same lever or actuator, but that can control two electrical circuits. The double-poles switch is commonly used in industrial applications but can be found in some house applications. Like the single-pole switch, a double-poles switch has on/off markings and controls a device or equipment from one location. The main difference is that a double-pole switch has four brass terminals, instead of two. Double-poles switches are commonly rated for 30 amps, compared to 15 or 20 amps with standard switches. This allows the switches to control power feeding higher-demand appliances, for example machinery motors.


10. What is the difference between single pole and double poles switches?

A switch pole refers to the number of separate circuits that the switch controls. A single-pole switch controls just one circuit. A double-pole switch controls two separate circuits. A double-pole switch is like two separate single-pole switches that are mechanically operated by the same lever or actuator. In summary, one pole can control one electrical circuit and two poles can control two electrical circuit.
