In order to enable motion, where must the DEADMAN switch be held?

• A. At the lowest point
• B. Centered
• C. At the highest point
• D. In the off position

Answer: (B)

The DEADMAN switch, which is a crucial safety feature in control systems, must be held in the centered position to enable motion. This switch is designed to prevent accidental or unintended movements of machinery. When the switch is centered, it allows the system to recognize that the operator is actively controlling the machine. If the switch were at the lowest or highest points, it would typically indicate a mode where the machine should either be off or in a specific operational state that does not allow for movement. Holding the switch in the off position would completely disable any motion, which is contrary to the requirement for enabling movement. Therefore, the centered position signifies that the operator is engaged and ready to control the motion safely and intentionally.
