PRESSURE SWITCHES
This type of pressure switch features a high degree of
miniaturisation and a modern attractive design.
It can be installed in any position and also mounted onto
a wall by means of two transversal holes.
In order to reduce wiring times, it is supplied ready assembled with a 2-metre electric cable or an M8 connector with
a 300-mm cable.
The contact is the switching type, which means it can be
normally open or normally closed.
A knurled push-lock handle is provided for regulation
