By working with the experts at GIGAVAC it's easy to select the right high voltage relay for your application. You only need to know a little about your contact load and whether the relay will be making and/or breaking the load ("hot' switching). If you would like to know more about the physics of our relays to gain a better understanding why we recommend certain relays for specific applications, please visit "Physics of High Voltage Relays".
Products & Services
Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other.
Reed relays are electrically-operated switching devices that consist of two thin, magnetic strips (reeds) encapsulated in a glass envelope. They are used to switch industrial components such as solenoids, contactors and starter motors.
Specialty relays and accessories are specialty or proprietary products and accessories related to relays.
Relay boards (multiple relay modules) are computer boards with an array of relays and switches. They have input and output terminals and are designed to control the voltage supply.
Overload relays prevent an electric motor from drawing too much current and overheating; includes thermal and solid state overload types.
