This is a general listing of [OEM] manufactures of Mechanical Relays (a Reed relay is a mechanical device). Solid State relays have no moving parts.

{Relay Manufacturers Index}



Solid State Relays [SSR] are bounce free, switch faster than mechanical relays, and have no moving parts. In most cases an opto-isolator is used to control a FET which would control the switching current.

ElectroMechanical Relay [EMR] is an electromagnetically-operated switch. An actuating current on a coil operates one or more galvanically separated contacts. This type of relay must make mechanical contacts in order to switch a load. These contacts are prone to oxidation breakdown, and bounce. However Reed relays are hermetically sealed and do not suffer from oxidization as much as open contact mechanical relays do.

Reed Relay Contacts are made from a ferromagnetic material (reed) which are encapsulated in glass. An energizing coil is wrapped around the glass and an EMF brings the two reeds together, closing the contacts. There are two types; Dry or Wet. Both types are identical except a Wet Reed relay has a small amount of mercury added inside the glass tube, providing a more consistent contact resistance.

Forms:
.. Form A: Normally open, when the relay is energized the circuit is completed [SPST, or DPST]
.. Form B: Normally closed, when the relay is energized the circuit is open [SPST, or DPST]
.. Form C: [SPDT]

Neutral: The transition from one switching position into another is independent of the direction of excitation

Polarized: The transition from one switching position into another is dependent on the direction of excitation

Monostable: The transition to one switching position due to an input excitation, only last while the input excitation is present, once the excitation is removed the relay returns to it's original position.

Bistable: The transition to one switching position due to an input excitation, once the excitation is removed the relay does not return to its original position. The relay requires another excitation to return to its original position

This is a general listing of Relay manufacturers and vendors. The listing is sub-divided into either mechanical relay manufacturers or solid state relay manufacturers. The types of products or devices the manufacturer produces are listed under the company name, in alphabetic order.
