Linear Power-Brake Switch

The whole Master Control unit is installed in the driver’s console.
The picture shows the component arrangement and dimensions of the power- /brake control
unit which is to be operated by means of a customer specified grip.
This grip consists of blank aluminum without any surface treatment.
As enlightens from these documents all snap action switches are wired up to a connector that
is located at the end of flexible connecting cable. A strain relief makes sure that the connecting
cable is properly fixed to the power- / brake control unit. The length of the flexible connecting
cable can be adapted according to the project specific requirements. The appropriate mating
connector is included in the scope of delivery.

A special connecting cable provides the electrical connection between the capacitive sensor,
the potentiometers (which are part of the power- / brake controller) and the interface module
that incorporates the following functions:

A 72V to 24 V DC/DC converter Two independent 4 – 20mA output devices.
The output device of the capacitive sensor which is used for automatic vigilance control
