Magnetic snap-action contact (normally closed or normally open)
The instruments are delivered with a single or double contact (normally
closed or normally open).
With 'normally closed', the contact ag is engaged with the limit switch and,
on rising pressure, disengages from the contact via the actuator attached to
the pointer. The circuit will be interrupted.
With 'normally open' the contact ag follows the pointer until the limit value
is reached. Once the limit value has been exceeded, the contact ag
engages and the circuit is closed.
The switching function of the switch is indicated by the index 1, 2, 12, 11
or 22.
