Magnetic Level Switch MOBREY M-SWITCH SMA1

A permanent part of a magnet forms float assembly
that rises and falls with the change of liquid level. One second
permanent magnet is placed on the switch or pilot air
valve, so that the adjacent poles of the two magnets repel
yes through a non-magnetic membrane. Change
of liquid level that the float moves through its allowable
trip will cause the electronic float to circulate and repel those
magnet to give fast acting performance.
The change is carried out by the angular movement of the
magnet switch is used to operate "push rods". These
bear bars on contact sheets and break a series of contacts
allowing at the same time as the other to do. The benefit of this
agreement is that the contact force is independent of the
magnet.
