ESSEN Sub-Miniature Micro Switches Type MV7N are designed for applications where low operating force is required. Moulded from flame retardant thermoplastic conforming to UL94V-O, these micro switches incorporate a long life high precision snap action mechanism. Their small size results in a considerable saving of space. These are available with solder or PC Board terminals fitted with either auxiliary plain or roller lever.
They are ideal components for use in communication equipment, vending machines, security systems, VCRs, cassette tape recorders, data systems and medical equipment.
These micro switches can be supplied with silver or gold plated terminals. While ordering, place 'S' for silver plated terminals and 'G' for gold plated terminals in bracket ‘( )’ against Cat Number of Micro Switch.. e.g. MV7NPS or MV7NPG, MV7NS or MV7NG, MV7NPSL7 or MV7NPGL7 etc..
