F-4 Floor Switch
The F-4 Leveling Switch, also patented January
1, 1924, has the same simple design and
dependability as the F-3. The difference is the
F-4 is strictly a leveling zone or inching switch.
An F-4 is mounted on the elevator car or
platform. The switch is mechanical and spring
loaded, operating off of a stationary cam at each
landing. The F-4 has two normally open
contacts, each one activated by a roller. When
the car stops at the floor the cam forces the roller
down causing the contact to be made. When the
cam hits the other roller it causes that contact to
be made. If both rollers are depressed at the
same time making both contacts, it signifies that
the car is in the leveling zone and the brake sets
to hold the car. If only one roller is depressed the
car will re-level or level in the direction of the
open contact, stopping when that contact is
made. This assures that the car is level within
the adjustable zone of the switch.
These are cast aluminum enclosures with sturdy
cast brass contact levers and contacts designed to
work at up to 250 volts AC or DC. The rollers
are mounted on brackets adjustable in
increments of 3/16". The stationary carbon and
copper contacts are heavy duty, long lived, and
reversible.
