HE5B SERIES
Part No :
HE5B
The HE5B is part of the enabling switch series. Also known as « Dead-man » or « 3-position safety » switches, the enabling switches allow the operator to work safely on a machine without disabling operation.
The use of an enabling switch stops the device in the event of a catastrophic failure or unforeseen problem.
