MICRO SWITCH™
BAF/DTF Series
High Capacity Enclosed Switches
DESCRIPTION
MICRO SWITCH BAF1 high capacity enclosed switches offer
elastomer boot on sealed actuator verions that protects the ac-
tuating mechanism and the internal basic switch from contami-
nants. There is a seal gasket between the cover plate and the
enclosures on all versions. The cover plate is removed for ease
of wiring and switch replacement without demounting the switch.
The actuator position is designated “right” or “left,” when looking
at the nameplate.
