Information

T73 relay is a small electromagnetic relay most commonly used in household appliances. It is widely used in various household appliance circuit boards such as rice cooker circuit board, induction cooker circuit board and electric kettle circuit board. Now it is also used in charging pile equipment. How is the T73 relay wired? Psychic relay editor will give you a brief introduction.

 

T73 relay has three pin positions, normally open, normally closed and conversion. T73 relay normally open type is the most widely used pin position. Normally open relay, in short, is disconnected in case of no power supply and pulled in after power supply. T73 normally closed relay is simply understood to be closed without power supply and disconnected after power supply. T73 conversion relay, many customers will call it SPDT relay. This contact group has three contacts, namely, the middle is dynamic contact and the upper and lower are static contacts. When the coil is not powered on, the moving contact and one of the static contacts are disconnected and the other is closed. After the coil is powered on, the moving contact moves to make the original disconnected closed and the original closed open, so as to achieve the purpose of conversion.

 

Let's look at the pin positions of these three T73 relays.
