Operator Switch (Propel Transmission) | |
This switch is a multi-pole multi-throw switch. The switch uses two contact blocks and an internal mechanism to actuate the contact blocks. The switch provides three inputs (Propel A, B, & C) for the ECM. The ECM constantly monitors the states of the inputs. If the inputs are in an invalid state, the ECM indicates that a circuit failure is present by logging a service code. See Systems Operation, "Diagnostic Operation" for more information.
The states of the switch inputs are sent to the ECM, and the ECM selects the gear for the propel transmission. Table 1 shows the states of the switch inputs for all valid positions:
| Switch Positions for the Operator Switch (Propel Transmission) (1) | |||
|---|---|---|---|
| Propel Transmission Gear | Input for Propel (A) | Input for Propel (B) | Input for Propel (C) |
| First Gear | O | O | C |
| Second Gear | C | O | C |
| Third Gear | O | C | O |
| Fourth Gear | C | C | O |
| ( 1 ) | O = Open (no continuity to return or ground). ______________ C = Closed (continuity to return or ground). |

This switch is a double-pole triple-throw switch. The switch provides three inputs (Rotor A, B, & C) for the ECM. The ECM constantly monitors the states of the inputs. If the inputs are in an invalid state, the ECM indicates that a circuit failure is present by logging a service code. See Systems Operation, "Diagnostic Operation" for more information.

Switch (Parking Brake) | |
This switch is a double-pole single-throw switch. The switch provides two inputs (Brake Release / Brake Application) for the ECM. The ECM constantly monitors the states of the inputs. If both inputs are in the same state (floating / grounded), the ECM indicates that a circuit failure is present by logging a service code. See Systems Operation, "Diagnostic Operation" for more information.
The states of the switch inputs are sent to the ECM, and the ECM controls the parking brake. When the operator applies the parking brake, the switch input for the Brake Application is closed to ground, and the switch input for the Brake Release is open.

This switch is a single-pole double-throw switch. The switch provides two inputs (Left Steering / Right Steering) for the ECM. The ECM constantly monitors the states of the inputs. If both inputs are grounded, the ECM indicates that a circuit failure is present by logging a service code. See Systems Operation, "Diagnostic Operation" for more information.
The states of the switch inputs (LEFT / RIGHT / HOLD) are sent to the ECM, and the ECM controls the rear steering. When the operator places the switch in the LEFT position, the switch input for the Left Steering is closed to ground and the switch input for the Right Steering is open. When the operator places the switch in the RIGHT position, the switch input for the Left Steering is open and the switch input for the Right Steering is closed to ground.

The switch detects the presence of metal or the absence of metal. When a metal object is within 5 mm (0.197 inch) of the switch, the switch is ON. A red LED in the switch is also ON. When no metal object is within 15 mm (0.591 inch) of the switch, the switch is OFF. The red LED is also OFF. In order to operate the switch, connect the battery positive terminal to Contact 3 (wire 119-PK), and connect the battery negative terminal to Contact 1 (wire 840-GN). Refer to the connector that is shown in Illustration 11.
The states of the switch inputs (LOCKED / UNLOCKED) are sent to the ECM, and the ECM controls the rotor lift lock. When the rotor lift lock is in the LOCKED position, connector J1-19 on the ECM is closed to ground and J1-20 is open. When the rotor lift lock is in the UNLOCKED position, connector J1-19 on the ECM is open and J1-20 is closed to ground.
