Push-Pull and E-Stop Switches Datasheet
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.
Features and Benefits 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.
