Electric Alarm Contacts

These contacts, fitted into the case of a thermometer or pressure gauge, are designed to open or close circuits from the instrument’s pointer position. Available in 100mm and 150mm up to 4 contacts.

Low Action Contacts

These contacts are used in absence of high contact loads and vibrations. The contact is instantaneously released upon touching of the two contact pins. These contacts are not suitable for use in high duty operation, aggressive atmosphere and measuring instruments filled with liquids.

Snap-Action Contacts (with screwed-in magnets)

This type of contacts can be used under almost all operating conditions and are generally not affected by vibrations. The contact release is accelerated by an additional skip or snap action when the pins are approaching.

Inductive Contacts

The gauges are equipped with non touching proximity switches. Due to their contact free operation, switching precision and long service life, these contacts are suitable for any industrial application and should preferably be used with oil filled measuring instruments. The output signal is determined by the presence or absence of a control vane moved by the instrument pointer within the electromagnetic field of the proximity switch.
