8.4 Two-hand control using mechanical switches with simulta-
neity monitoring
Two-hand control with mechanical switches / safety relay for mechanical switches
or 2-channel fail-safe sensors/switches with contact output with simultaneity
monitoring�
The contacts of the mechanical switches must allow a minimum current of
6 mA�
8.4.1 Connection
Connection of two mechanical fail-safe switches
This wiring (with only one normally open contact per sensor/switch) meets the
