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

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

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

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

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

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.

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

Level transmitters or level transducers are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space. For each measurement, they provide an electrical output that is proportional to the input level.

Magnetic field sensors measure magnetic field strength, direction, and/or magnetic flux. They are used for scientific measurement, navigation, and industrial applications

Gas flow switches and liquid flow switches, velocity, are used to measure the flow or quantity of a moving fluid in terms of velocity, such as feet per minute

Emergency stop switches are devices that users manipulate to initiate the complete shutdown of a machine, system, or process

Pushbutton switches are mechanical switches defined by the method used to activate the switch. The activation method is typically in the form of a plunger that is pushed down to open or close the switch
