Solid state relays (SSR) or semiconductor relays are semiconductor devices that can be used in place of mechanical relays to switch electricity to a load in many applications

Time delay relays and solid state timers use solid state electronic devices to provide a time delay

Reed relays are electrically-operated switching devices that consist of two thin, magnetic strips (reeds) encapsulated in a glass envelope.

Relay sockets are devices that accept relays, electromechanical switches in which the variation of current in one electric circuit controls the flow of electricity in another circuit

Specialty relays and accessories are specialty or proprietary products and accessories related to relays

Overload relays prevent an electric motor from drawing too much current and overheating; includes thermal and solid state overload types

Mechanical testing equipment covers devices used for adhesion, compression, drop (shock), tensile, vibration and fatigue testing
