Park Brake Switch - Toro Z Master Z400 Series Service Manual

Fig 390
How It Works
This single pole plunger (normally open) type switch
has two terminals. When the motion control handles
are in the neutral position (handles in the out position),
it pushes on the plunger, closing the contact and
connecting the terminals (Fig. 391).

Testing
1. Disconnect the switch from the wiring harness.
2. Using a VOM or test light, check first to ensure there
is no continuity between the terminals, plunger out.
3. With the plunger pushed in, there should be
continuity between the terminals.
