Switch inputs provide one of these input signals to implement ECM:
Switch inputs are two-state equipment. Switches are either open or closed.
When a switch is open, no signal is provided to corresponding implement ECM input.
When a switch is closed, either a ground signal or a +battery signal is provided to cor-
responding implement ECM input.
Switches may have a combination ofswitch inputs in one component.
Implement Control Switches.
