DP MCB In Two Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls two Circuits at the same time. In terms of Residential Switching, this Normally means it Switches the live and Neutral at the same time. In Layperson Terms, Double Pole switches or DP Switches are Exclusively Designed to Control two Different Electrical Circuits at the same time, which allows the Appliances to Isolate in a safe and reliable manner. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches.

An SPST (Single Pole Single Throw) Switch is a Switch That only Has a Single Input and can Connect Only to one Output. This means it Only Has one Input Terminal and Only one Output Terminal. A Switch is a Mechanical or Controlling Device That Changes the Flow of Current Direction or Interrupts the Flow of Current Within a Circuit. Single Pole Single Throws (SPST) is Perfect for on-off switching. When the SPST is closed, the Circuit is Closed and the light from the lamp switches on. When The Single Pole Single Throw (SPST) is then opened, the light from the lamp goes out and the Circuit is off.
