Question

Write the
different types of switch.​

Answer 1

Answer:

There are many different types of electrical switches. Switch function is defined by the number of poles and throws the switch has. “Poles” are individual circuits the switch controls (e.g., a “3-pole” switch has three circuits controlled by the same throw). “Throws” are unique positions or settings for the switch (e.g., a “double-throw switch” can operate in two different positions like on/off, high/low, etc.). Combining the number of poles and throws gives a succinct description of the switch’s function, so the function of, for instance, a “single-pole, double-throw” switch is implicit. Switch types are commonly abbreviated for brevity, so a single-pole, double-throw switch would be referred to as an “SPDT” switch.

The simplest type of switch is a single-pole, single-throw (SPST) device that functions as an on-off switch. Double-pole, double-throw (DPDT) switches are commonly employed as internal polarity reversing circuits. Switches of up to four poles and three throws are common and some have breaks.
