KW4A(S) Fax Machine Micro Switch with UL CUL Wholesale

Micro switches can be used to control the paper feeding process. When the fax machine needs to send paper to the scanning head or printer, the micro switch will sense the position of the paper and send a signal to the fax machine controller, so as to realize precise paper feeding control. The micro switch has a variety of contact terminals and levers. It is long life and high reliability.  And our switches applied for many international certifications to meet different requirements.
