A switch is an electromechanical device used to control the flow of electricity in a circuit. When the switch is ‘OFF’ or in the ‘open’ position, there is no flow of electricity. When the switch is ‘ON’ or in the ‘closed’ position, electricity flows. An electrical switch typically includes an actuator, a moving contact, terminals, and a case or housing. TE switches are cost-effective, reliable, high-performance solutions designed to withstand extreme shock, vibration, temperature, and altitude. Our portfolio includes switch accessories, such as knobs, caps, boot seals, and hardware. Our electrical switches are used in industrial machineryroboticsappliancescontrol panelsmotion control systems, and building, lighting, and HVAC systems. Shop our switches by brand: ALCOSWITCH switches and AMP switches.
