Mechanism & Circuit Examples of Electric Contactor
Illustration Thermometers with contactor have made possible automation of temperature control and increased the safety of energy consuming.
Electric contacts are switching mechanisms designed to be actuated by travel of thermometer indicating pointer. Points where the switch will open or close are regulated by adjustable (or fixed) "set" hands.
Thermometers equipped with this optional feature will turn alarm signals "on" or "off", as each set-hand switching point is reached. And, where appropriate relays are incorporated in the installation circuit, contacts will turn electric motors, heaters, valves, etc. "On" or "Off".
Upper limit one contact
Lower limit one contact
Upper & Lower limit two contacts
