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.

Improved visibility with full-color LEDs

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)

Lightweight and Compact Case

The case size has been reduced to approximately half compared to the Electrical Switch 3. This allows for easy installation even in machines with limited mounting space.

Two Types of Bottom Cases to Choose From

Two types of bottom cases are included: one with mounting holes and one without. You can switch between them to suit your installation method.

Black Servo Leads for High Current

The black cables not only give a sleek appearance but also ensure the necessary current capacity while providing optimal flexibility for easy handling.

Note: Be sure to remove the battery after using and when storage.
Because, Circuit of products are using current when even power off.
So,if this situation are long time, battery will be over discharge and broken.
