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

Disconnect switches rapidly disconnect from power supplies in the event of an emergency

Terminal blocks are modular, insulated blocks that secure two or more wires together. Terminal blocks consist of an insulating body and a clamping device. Their flexibility allows wiring to be centralized and makes it easier to maintain complex control circuits.

PCB terminal blocks are modular, insulated devices that mount on printed circuit boards (PCBs) and secure two or more wires together. Some have integral pin terminals and mount through holes in the board. Others plug into PCB-mounted pin strips.

Air valves allow metered fluid flow in one or both directions. They are used in pneumatic circuits to regulate the rate of activation or exhaust of cylinders and other pneumatic devices.

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

Knife blades are sharp-edged industrial tools for shearing or cutting materials. A blade uses an edge to fracture and slice threw a material. A knife blade can be "toothed" but it still uses pressure against its edge as the primary means of cutting

Switch boots protect switches from contaminants such as dirt, dust, gas, and liquids.  They are generally tough, pliable silicone rubber devices for toggle, pushbutton, rocker and rotary switches

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

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

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

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. 

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

Rocker switches are actuated by a standard or dual rocker or paddle

Toggle switches are actuated by moving a lever back and forth to open or close an electrical circuit
