299-0326: Relay

Description: Cat® Relays are switches controlled by electrical power, like another switch, computer or control module. The purpose of an automotive relay is to automate this power to switch electrical circuits on and off at particular times. Application: Most common application of automotive relays, see collection, is to switch a high current circuit using a low current circuit. This application comes into play whereby an in-line switch does not have the capacity to handle the current required to switch a high current electrical system. Consult your owner's manual or contact your local Cat Dealer for more information.
