KO Propo Electrical Switch 4

This is an electronically controlled power switch unit. It uses a CPU to memorize the power state (ON/OFF), preventing power interruptions caused by temporary disconnections due to GP car-specific vibrations or momentary disconnections during overloads.

Full-color LEDs are used to indicate battery mode (cut-off voltage) and remaining battery level, allowing the switch status to be identified at a glance. Additionally, high-brightness LEDs have been adopted for easy visibility outdoors or when installed on a machine.

Battery Mode Indicator

The type of battery connected to the Electrical Switch 4 and whether the voltage monitoring function is active are displayed using LED colors and lighting patterns. The Electrical Switch 4 is equipped with a monitoring function that cuts the switch when the battery voltage falls below the specified threshold to prevent over-discharge. Since the cut-off voltage differs depending on the battery type, users can switch to the appropriate battery mode for their application. Additionally, it is possible to specify whether the cut-off function is enabled or disabled.

Blue: LiPo Mode (Cut-off Enabled/Disabled)
Green: LiFe Mode (Cut-off Enabled/Disabled)
Orange: NiMH Mode (Cut-off Disabled only)
(Default Setting: LiPo Mode (Cut-off Disabled))

Power Level Indicator

The remaining battery level is displayed using LED colors. The LED changes from "Blue" for fully charged to "Green," "Orange," and finally "Red" as the battery is used.

Blue: Fully Charged
Green: Slightly Used
Orange: Low Battery
Red: Charging Required (below cut-off voltage threshold)
