This Speed Switch is a direct equivalent to the        LS–20–A (3177)

The Unit was designed to switch selected equipment (such as Reversing Cameras) Off at a specific Road Speed.

The switching off speed is set by selecting a combination of up to 6 switches, giving 64 options between the limits of 2.5km/h (1.6mph) and 102.5km/h (64mph).
