EAO – Your Expert Partner for

Human Machine Interfaces

EAO – the expert partner for Human Machine Interfaces – has launched

a new compact stop switch with an ultra-low, less than 19 mm back

panel depth. The new Series 51 Stop Switch utilises a mono block

design with an integrated switching element to set a new space-saving

standard for industry.

The mono block design minimises the back panel depth and offers an

extremely rugged construction that protects the switch from damage

caused by heavy-handed use, or operator abuse. The ground-breaking

design has been tested beyond 100,000 actuations, so it’s a genuine

fit-and-forget product.

Main features
