Aerospace contactors are high-performance, high-capacity circuit controls designed for aerospace applications

Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other.

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.

Suppliers of membrane switches and keypad assemblies using flexible membranes, domed or flat switch profiles, and tactile and non-tactile switches and panels.

Motor starters and contactors are motor-starting devices.

Motor contactors are relays with large current capacity for connecting and disconnecting a motor from the power supply.

Rotating biological contactors are large discs on rotating shafts that are mounted in wastewater tanks, but only partly submerged.
