Electrical Contact Switches for pressure gauges switch depending on the direction of movement. This will open or close electrical circuits at the set limit values by means of a contact arm which is moved by the gauge pointer. These can be single or double contact, supplied with a metre of cable and an adjustment key to be set by an end user.
