More About Relays

Relays are electrically-operated switches that regulate power to downstream circuits when energized to control low-current equipment, devices, machinery, and electrical systems. 

  • General purpose and power relays use input signals and low voltages to control larger circuits. 
  • Time-delay relays open and close their contacts at preset times. 
  • Monitoring relays detect changes in operational or environmental conditions and protect downstream equipment from damage. 
  • Safety relays monitor operational and environmental conditions and disrupt power to protect workers. 
  • Solid-state relays have no moving parts and provide long service lives. 
  • Alternating relays toggle between loads to sequence load matching and distribute equal run times. 
  • Automotive relays regulate the flow of power through circuits to control vehicle components. 
  • Relay sockets mount on surfaces to interface relays with electrical connections.
