Reed switches are magnetically actuated switches. They are typically manufactured with two ferromagnetic reeds (contact blades), which are sealed in a glass capsule. In the presence of a magnet, the blades (contacts) close. 

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

Switches are devices that allow electric current to flow when closed and prevent current flow when opened. Switches, All Types are a high level search form that includes options for all switch types. Search forms for specific switch actuator types are also available

Liquid level switches are used to detect specific liquid levels or interfaces between liquids. These level measurements are indicated via an electrical switching action

Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes. They are typically used to control heating and cooling systems

CompactPCI switches and PXI switches are used in industrial systems to connect test points or devices to instruments for the purpose of testing, measuring or monitoring the system

Matrix switching systems rout signals (RF, video, audio, data, and others) from multiple inputs to multiple outputs

High voltage relays are used to transfer power for high voltage and high frequency applications. They are heavily insulated and consist of strong materials to increase contact life.

Dry material (powders) level switches are used to measure levels of dry, solid materials via an electrical switching action

Magnetic proximity sensors include devices that work on inductive, variable reluctance, magneto resistive or Hall effect principles. Proximity sensors detect the presence or absence of an object using a critical distance.

Thermal cutoffs and thermal protectors are nonresetting, thermally sensitive devices designed to protect domestic electrical appliances and industrial equipment from fire. They are sometimes described as thermal one-shot fuses.

GPIB switches enable several GPIB controllers to share one or more GPIB devices. They also allow a single GPIB controller to operate multiple GPIB bus systems

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

Electrometers are instruments that measure electric charge and/or electric potential difference.

Liquid leak detectors sense when a liquid is leaking from a pipe, tank, or other receptacle area.
