RE: Dry Contact
Dry contacts are generally more versatile but it does require the sensing or switched device to provide the power supply. Take care to understand the ratings of these contacts. The are rated for voltage, current and switching capacity. CAUTION: The switching capacity is generally less than the combination of the rated current and rated voltage. Be sure the contact is appropriate for the circuit you are connecting it to.
In Europe, a dry contact is called a volt-free contact.
Hope this helps.

Dry contact. One through which no direct current flows.
Examples: Home toggle switch in rooms, electromechanical circuit breaker, electromechanical relay, switchgear, flash light switch, etc.
