Contactless switch conversion circuit b

Non-contact switching refers to electronic switches (such as solid-state relays , power electronic devices, 豱 shed Ping Yang Hui, Sheng Qu # mangluchuge).
Non-contact switches usually have no auxiliary mechanism
, and their switching state
is not . Therefore, the isolation circuit is an important part of
its signal conversion circuit
. The collection method of non-contact switch is
the same as that of contact switch,
that is, the non-contact switch is regarded as a contact
switch , and
the circuit Yes. It should be noted that
the connection polarity cannot be changed at will.
