MICRO SWITCH™ AC Series Door Switches
When the application is more complex than a “stand alone” switch can provide, consider the MICRO SWITCH™ AC
Series Door Switch. The AC Series switch assembly monitors the position of a service door or panel whether “closed”
or “open”. The AC Series switches are a compact switch assembly designed for equipment applications ranging from
vending machine service doors or panels, monitoring doors for truck trailers, and military-related doors and/or panels.
When the equipment (door or panel, etc.) which is electrically interlocked through the AC Series switch is opened, the
action of the AC Series switch disconnects the electrical power. The AC Series switch can provide an electrical signal
to an annunciator circuit such as a light or horn indicating the door or panel is open. Another feature that is common
to most AC Series switch assemblies is a “pull-to-override” position which allows the service door to be open and yet
apply electrical power through the switch assembly. The “pull-to-override” switch position could be useful for trouble
shooting equipment as required.
AC Series switch assemblies are available with up to four switch elements which can provide discrete outputs as
required for control and/or indicator circuits. Select catalog listings are available with UL and CSA agency certification.
Where the application is military related, catalog listings are available with a military specification part number.
What makes our switches better?
Available with Honeywell MICRO SWITCH™ V3, V7, SM, SE, or
BZ Series switches; there are no exposed contacts
Temperature ranges (-40 °C to 85 °C [-40 °F to 185 °F]) allow for
reliable performance usage in harsh conditions
Many catalog listings have internal threaded actuators that allow
customers to attach auxiliary plungers
Choice of switch actuation: two position momentary, two position
momentary with a twist-latch feature, or a three position with push
momentary and pull maintained action
Right form factor combined with
the right operating characteristics
make a precise combination for
door switch applications.

Features
and Benefits
RELIABLE PERFORMANCE
The switch automatically disconnects electrical power to equipment when service
door, panel, or drawer is opened.
CHOICE OF SWITCH ACTUATION
Choose the standard switch assembly with one of three mechanical positions:
push-momentary with a pull-to-override maintained position, the two position
momentary switch assembly, or the two position switch assembly with a push-
momentary and a push-and-turn-to-latch maintained position.
Enhanced switch offerings
MOUNTING EASE
The switch assembly is designed to be installed as a side mount or end mount for
versatility.
WIDE ELECTRICAL RANGE
Wide range of current from less than 1 A to 21 A to interface with control and
signal circuits.
Tough answer for tough door interlock needs
AGENCY CERTIFICATIONS
Select switch assemblies are certified to CSA and UL component recognition
where agency certification is desired or required. When the application involves
military requirements, several different styles of AC Series door switches are offered
with military specifications.
CIRCUIT FLEXIBILITY
Switch assemblies are available with single throw or double throw action with up to
four poles to provide control circuits and optional signal circuits as required.
TERMINATION OPTIONS
Two different types of switch termination (screw or quick connect blades) are
available to meet machine design requirements.
