An electronic switch manually or automatically creates or breaks an electric circuit. The ON/OFF mechanism serves as the foundation for its operation. Different switches are used in electrical or electronic circuits to activate or regulate the circuits. A switch’s type is determined by its connections in the circuit. A switch’s fundamental parts, such as pole and throw, determine the connections it can make and describe the variations in switch contact.
Types of Switches
Single pole single throw, single pole double throw, double pole single throw, and double pole double throw are the four primary types offered by switch manufacturers in mumbai.
SPST (Single Pole, Single Throw)
This is a basic ON/OFF switch. It is used to either open or close a circuit between two terminals. This switch supplies the owl circuit’s power source.
It has both an input and an output. This light switch establishes a single connection and regulates a single cable. Since the switch in the circuit below is an ON/OFF switch, when it is closed and set to the ON position, electricity flows between the two terminals, and the circuit bulb blinks. However, no current flows between the two terminals while the switch is open or off.
SPDT or Single Pole Double Throw Switch
These kinds of light switches have three connections. One of these three terminals is used as an input, and the other two are used as output terminals. A common terminal is connected to one of the two terminals. The SPDT types of light switches only use the COM terminal in addition to the other terminals.
These switches are mostly used in three-way circuits to switch on or off a lightbulb from two separate places, such as the top or bottom of a staircase.
DPST (Double Pole, Single Throw)
This switch has two poles, meaning it has two identical switches side by side. It is operated by a single toggle, which enables simultaneous regulation of two distinct circuits with a single push.
This switch is used to switch on and off two circuits. There are two inputs and two outputs on each of the four terminals. This switch’s primary purpose is to control 240V appliances, which necessitates the presence of both supply voltages while allowing an impartial wire to remain connected constantly. The two circuits will both get current if this switch is switched ON. There is no current flowing through the circuits while it is off.

DPDT (Double Pole Double Throw)
The two inputs of each circuit are connected to one of the two outputs through two independent circuits, equivalent to two SPDT switches combined. Depending on the switch’s position, every contact can be routed from the two contacts in any number of ways.
In ON-ON or ON-OFF modes, this switch operates as two independent SPDT switches controlled by a single actuator. Only two loads can be active at once. These kinds of electrical switches can be used in any application that calls for a closed and open wiring system.
