MICRO SWITCH™

BAF/DTF Series

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

of wiring and switch replacement without demounting the switch.

The actuator position is designated “right” or “left,” when looking

at the nameplate.
