Steering column switch

Vehicles are required to have a direction indicator light on each side at the front and rear. When used, these must illuminate with a frequency of 1.5 Hz (± 0.5 Hz) = 90 x per minute (± 30 x) on both sides simultaneously. The indicators are operated with a steering column switch on the steering column. The indicator switches automatically return to the original position, i.e. when steering out of the bend, the switches are automatically returned to the neutral position which means that the indicator is switched off.

The switch is returned to the original position with a tappet on the steering column which triggers a little lever on the indicator switch and causes it to return using spring force. When this happens, a switch is opened and the connection to the electronic control device (indicator unit) is interrupted and the process is ended.
