Actually, The question is incorrect. All of the transistors
can be used as a switch because transistors has current
on/off properties.There are 2 types of transistors one is
BJT(3 Terminal) and FETs(4 Terminal). BJT has low conduction
loss but has high switching losses whereas a FET
specially(IGBT or MOSFETs) have low sitching losses. That is
why MOSFET is preferred as switches instead of BJT in High
power, High Frequency applications.
