Switch

9.2.2.1

Description

Purpose
The switch is an operating element and display object with two states: "pressed" and
"released." Switches can signal the status of a system component that cannot be seen from
the HMI device, e.g. a motor. You can also change the status of this system component at
the HMI device.
A switch has two stable states. When you actuate the switch, it changes to the other state.
The switch retains this status until the next operation.
Layout
A switch can be labeled with a descriptive name, e.g. "Motor 2", and/or the names of its two
states, e.g. "ON" and "OFF". The switch can be positioned vertically or horizontally.
