Honeywell 10002/1/2 Run/Stop Key Selector

The Honeywell 10002/1/2 Run/Stop Key Selector is a rugged, industrial-grade mechanical selector switch designed to provide secure manual control over system operational modes—specifically transitioning between RUN and STOP states. Engineered for use within Honeywell’s safety and automation systems, this key-operated selector is often deployed in applications requiring a physical lockout mechanism for maintenance, operational override, or supervisory control.

Housed in a robust enclosure and equipped with precision key actuation, the 10002/1/2 is particularly favored in critical process environments where unauthorized access must be restricted. Whether used in hazardous process plants, energy production, or high-reliability automation, it provides an essential layer of control and safety integrity.

Frequently Asked Questions (FAQ)

1. What is the function of the 10002/1/2 Key Selector?

   It provides manual control for RUN and STOP modes using a key-operated rotary switch.

2. Can the key be removed in both positions?

   No, the key is removable only in the STOP position for safety and lockout control.

3. Is the switch suitable for outdoor use?

   It is rated IP65 on the front face, making it suitable for protected outdoor or panel-mounted use.

4. How many keys are included with the module?

   Two identical keys are supplied with each unit.

5. Can this selector switch handle both AC and DC loads?

   Yes, it can handle up to 5A at 250 VAC or 30 VDC.

6. Is the selector momentary or maintained?

   The 10002/1/2 has maintained (stay-put) positions for RUN and STOP.

7. What is the lifespan of this switch?

   It is rated for over 500,000 mechanical operations under normal use.

8. Can I mount this on any panel?

   Yes, it fits into a standard 22 mm diameter cutout.

9. Is it compliant with safety standards?

   Yes, it meets CE, UL, and CSA safety certifications.

10. Can I use it in an intrinsically safe zone?

    While robust, it is not intrinsically safe; consult Honeywell’s hazardous area models for those applications.
