Push-Pull and E-Stop Switches
Honeywell Push-pull and E-stop switches are durable, environmentally sealed, sliding contact switches
incorporating two circuits with multiple combinations. The sliding contacts provide positive contact closure
and opening when the switch knob is operated.
The dual O-ring design protects the contact chamber by isolating it from any moisture or any other
contaminant. These Push-pull and E-stop switches are available as two-circuit switches. Contact closures
are available with both circuits closed in the push position, both circuits closed in the pull position, or
alternate closure: one closed and one open.
These switches can be a replacement for sealed and unsealed switches including power take-off switches
and park brake switches. These rugged and reliable switches increase application reliability and facilitate
seamless equipment operation and control with their ability to keep dirt and moisture out of the contact
chamber, thereby promoting longer switch life.
Multiple standard knob colors are available with these switches and can be shipped in bulk packaging.

ENVIRONMENTAL PROTECTION
Honeywell Push-pull and E-stop switches are designed and tested to withstand a
wide range of environmental conditions and contaminants: severe temperatures,
chemical splashes, pressure wash, vibration, dust, humidity, and salt.
IMPROVED DURABILITY
The dual O-ring design protects the contact chamber by isolating it from moisture
and/or any other contaminant.
NON-CONDENSING CAPABILITY
These Push-pull switches can be operated in humidity range of 5 %RH to 95 %RH
and are designed for severe temperatures.
SLIDING CONTACTS
The sliding contacts provide positive contact closure and opening when the switch
knob is operated.
