    Hello guys ,
    I work as a Product Designer in India. Recently became a member of this group .
    Here is my query for all you Electrical and Electronics people .
    I am looking for a Component which can control the Out put of a 3.7V battery. Similar to a Fan regulator.

    My Product had TEC's which are powered by Battery to Heat up.
    I need Three Different levels of Heating and On/Off functions.

    Kindly suggest me what I can do to achieve the same.
