MICRO SWITCH Miniature Toggle Switches
MT Series
DESCRIPTION
Honeywell MICRO SWITCH MT Series miniature toggle
switches are designed to meet the need for a rugged, cost-
effective toggle switch. Quality construction features include
a seal between the toggle lever and bushing, and between
the cover and case. These switches are designed for use in
applications in many demanding outdoor environments, where
the panels are subjected to such things as vibration from
equipment, temperature extremes, dust, splashing water, and/
or hose directed water.
They are capable of withstanding exposure to heavy
accumulations of early morning dew that may condense on
the control panel in cabs of vehicles left outdoors overnight.
The MT toggle switches with metal or plastic levers are well
suited for gloved-hand operation.
The panel stand-off with O-ring feature available on some
listings eliminates the need for behind-the-panel hardware,
provides a uniform panel height, and a panel-to-cover seal.
VALUE TO CUSTOMERS
• Spring-loaded mechanism provides enhanced tactile
feedback for toggle switch lever
• High sealing level and electrical life cycle enable more
uptime in field installations which helps in keeping
machines working longer with less downtime
• Small size allows for smaller control box/panel size to reduce
weight and operator fatigue
FEATURES
• Miniature behind-panel size (case) enables overall control
box or panel use
• IEC 605292001, IP67, IP68 (except terminal parts) sealing
for harsh-duty applications
• Up to 60,000 electrical life that enhances the use time
• Available with 8 circuitry options
• 2 or 3 position maintained and momentary action to meet
circuit and actuator requirements
• UL recognized, CE certified for global use
POTENTIAL APPLICATIONS
Remote control box of
• Concrete pumping
• Cranes
• Material handling
• Boom trucks
• Any application with small panel constraints
DIFFERENTIATION
• 60K life cycle offers an enhanced application life, keeping
maintenance, replacement, and refurbishment at a
minimum
• High seal rating (IP68) to protect the toggle from water
ingress and support more equipment uptime
