What is a deadman switch?


The deadman switch is a servo power ON/OFF switch located at the back of some teach pendants. Its purpose is to safeguard the robot operator during the training phase.

While in teach mode, robot servo power remains on while the deadman switch is pressed. However, the power shuts off when the deadman switch is released. During manual manipulation or block operation, the operator can immediate stop the operation by releasing this switch.
