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

Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. 

Level switches is a generic search form for devices that are used to detect liquid or powder levels, or interfaces between liquids. These level measurements are indicated via an electrical switching action

Linear position sensors, all types, is a general search form for all linear position / displacement detection product areas

Level sensors are used to detect liquid or powder levels, or interfaces between liquids. There are two basic level-measurement types: continuous and point or multi-point

Proximity sensors, all types is a general search form for all proximity sensors and presence detection product areas

Touch-sensitive and tactile switches operate by touching or pressing to make a connection. Touch-sensitive switches are touch-operated switches that do not have moving parts, while tactile switches are electromechanical and provide tactile feedback

Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement).

Specialty or proprietary products and accessories related to switches

Safety sensor switches are placed in enclosures to prevent accidental contact with live electrical connections

Network switches route packets between ports at the OSI layer 2, which means that (in Ethernet) the switches decide where incoming packets are transferred to, based on the NIC's 48-bit address

Signal switches activate or deactivate a signal once an event has occurred

SCSI products is a general search form that covers small computer systems interface (SCSI) products such as SCSI host adapters and controllers, converters, terminators, and switches.  More detailed search forms are available for individual areas

RF switches route radio frequency signals to particular waveguides

DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies
