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.
