I am looking for a contactor or relay that has the following characteristics:
1) silent or nearly silent in operation. 2) Be able to handle 20 amps of current. 3) be available in a variety of coil voltages including 120VAC. 4) Cost no more than $30.00 each 5) Rated for continuous duty use. 6) Operable in any position.Does anyone have any suggestions?

Does anyone have any suggestions?

As I understand it, contactors are used for loads like motors that draw high starting currents, or that have inductive kickback when turned off. That is, loads that are hard on "normal" relay or switch contacts.
What is your load? Do you actually need that level of protection? If not, then you might be well satisfied by solid state relays (SSRs). Many available in that price range.
