To initiate a jog movement, the DEADMAN switch must be fully pressed.

• A. True
• B. False
• C. Not required
• D. Only with safety interlock

Answer: (B)

Jogging is controlled by a safety feature that requires the operator to indicate intent by using the deadman switch. The important point is that motion is allowed only while this switch is engaged, and you typically must keep it pressed to continue jogging. Releasing the switch stops movement. The exact mechanical travel of the switch isn’t what enables jogging—it’s the state of engagement. Some setups may add an extra jog-enable step, but the need to press to the maximum depth isn’t a universal requirement. Therefore, saying you must be fully pressed isn’t universally true; you just need to engage the deadman switch and keep it engaged during the jog.
