ergonomic design that means the Salus20 has no potential areas
for dirt to collect and trap. The Salus20 is also tted with stainless

Application
A typical application of Salus20 isolator key switch is
machine guarding. It is usually used in combination with
an access interlock such as the Salus for part body
access or an acces interlock with an exchange key for
full body access control.
The Salus20 breaks the machine safety circuit, ensuring
a machine is shut down when the key is turned and
removed. The key can then be taken to the Salus
automatic access interlock to enable access to the
machine.
The machine cannot be restarted until the door is closed,
the bolt is trapped in the access interlock and the key is
removed and taken to the Salus20 key isolator switch.
