Editing Dead man's switch (section)

===Seat switches===
The dead man's switch can also be located beneath the seat of a vehicle or machine and engages if the operator is not in the seat holding the switch down. On modern tractors, the switch will cut the engine while the transmission is engaged or the [[power take-off]] is spinning. On riding lawn mowers, the switch is often more extreme where the switch will cut the engine even if the mower is parked and the blades are not spinning. Seat switches can also be used to keep small children from even starting the vehicle since they would not weigh enough to completely hold down a switch adjusted to an adolescent's or adult's weight.
