Starter Solenoid
The starter solenoid acts as a high-current electromagnetic switch. Failure typically occurs when the internal copper plunger contacts oxidize or the electromagnetic pull-in coil suffers an open circuit, preventing current from the battery from reaching the starter motor despite the key being turned.

Ignition Switch
The ignition switch is a mechanical rotary contact system that initiates the starting sequence. Over time, moisture ingress or repeated high-cycle use leads to internal contact pitting and mechanical wear, which prevents the 'Start' terminal from establishing a circuit with the battery terminal when the key is rotated.

Parking Brake Safety Switch
The Z345M uses a series of safety interlock switches as logic gates to prevent accidental starting. If the internal spring or plunger mechanism of the brake switch fails in the 'open' position, the starting circuit cannot be completed, resulting in no response from the solenoid when the key is turned.
