Changeovers

These thermal switches are used for monitoring/controlling temperature without an electricity supply. Changeovers are thermal switches with a changeover contact.

With a changeover, the circuit is switched upon reaching a temperature that is too high or too low within a predefined temperature range.

This type of thermal switch can typically be found as a form of ventilation control in fan ovens.

Special models for specific applications are available on request.
