Double pole Single Throw switches are sometimes called DPST switches. Assuming the circuit is single phase two wire system, DPST - are used to isolate the ciruit. Isoloation occurs on both terminals hence it is called double pole. This isolation occurs at only one end in the circuit, hence it is called single throw.

What is the main purpose of SPST and DPST switches?
An SPST switch can break the connection or hold the connection depending on which switch your using.
What is a closed switch?
A normally closed switch is a switch that is normally closed. When you operate it, it opens.
How does push to make switch work?
Push-To-Make switch is a switch in which pressure is applied to the switch for it to let the electricl current flow through.
What are switch legs?
When the neutral wire goes to the switch
How do you connect an ON-OFF switch to control the light?
To control a light with a switch, the switch has to be connected in series with the light fixture.
How do you install a switch for a 240 volt motor?
Use a DPST - A two pole switch.
How do you wire a DPST switch?
A double pole single throw switch. used to switch two lines at the same time.
How is the 2-way circuit diagram of power switch?
By using DPST(Double Pole Single Through) switch.
What is the main purpose of SPST and DPST switches?
An SPST switch can break the connection or hold the connection depending on which switch your using.
What is a DPST switch?
DPST is short for double pole, single throw. Double pole means that the unit contains two identical switches, side by side, and operated by one single toggle or lever. This means that two separate input wires can be controlled by a flick of one toggle. Single throw means that each switch can make or break a circuit; it can connect the input wire to the output, or not. It can't connect to one or other of two output wires, switching between them. A DPDT switch is also used for a disconnecting a 240 volt supply from a 240 volt load. Some other types of switches are Single Pole Single Throw (ordinary light switch), Single Pole Double Throw, Double Pole Double Throw, Triple Pole Single Throw and Triple Pole Double Throw
What does double pole single throw means?
DPST is like two SPST that are actuated by single switching mechanism. In other words two switches turned on/off by one lever action or push button.
What is the switch objective?
A switch can be used to switch on and off electricity. Or switch could mean to switch rails on the railway. Or switch could be to change jobs, task, hobbies, and so on.
Can a single pole switch can be use as a dimmer?
No a switch just opens and closes a circuit. A switch can be replaced by a dimmer switch. The dimmer switch will fit in the same enclosure that the switch is removed from.
What is a DUD switch?
a switch which is given as a optional switch to switch on or off something but doesn't actually work.
What is a closed switch?
A normally closed switch is a switch that is normally closed. When you operate it, it opens.
Pressure switch does not switch off?
switch is frozen from water corrosion.
What is a Synonym for switch?
electric switch, electrical switch, control, controller
