Setup
a) Connection
• Connect the connector of the battery port (3) to the corresponding connection on the battery
pack.
• Connect the connector (4) to the corresponding connection on the consumer.
b) Power ON
• Press and hold the on/off button (6) for 1 second to switch the electronic switch on. The battery
capacity indicator lights up and shows the status of the battery. (For detailed explanations of
LED statuses, please see the “Battery capacity indicator” section).
c) Power OFF
• Press and hold the on/off button (6) for 3 seconds to switch the electronic switch off.
• Always disconnect the battery and the electronic switch after use. This is because the switch
will continue to consume current (although it’s a very small amount) if it’s still connected to
the battery (even if the switch is turned off). Maintaining the connection long term can cause
complete discharge of and damage to the battery.
d) Switching modes
You can monitor the discharge of NiCd/NiMH batteries in normal operation after switching on.
If using LiPo batteries, switch the mode to LiPo mode.
The on/off switch automatically protects the battery cells from over discharging. As soon as the
available cell voltage drops below 6 V, the on/off switch switches the power ow off. It switches
back on again as soon as the voltage exceeds 6 V.
The reaction of devices connected to the battery may be slowed due to use of LiPo
mode.
• Press and hold the selector button (5) for approx. 1 second to switch to LiPo mode. The
LED (2) lights up.
• Press and hold the selector button (5) for approx. 1 second to switch to normal mode. If the
on/off switch is in normal mode, this LED (2) does not light up.
e) Battery capacity indicator
The battery capacity indicator (1) shows the battery status with the aid of a colour scheme. The
following gure shows the assignment of the individual colours to voltage values (red, yellow
and green).

Operating instructions
Electrical on/off switch with LED
Item No. 1877011
Intended use
The product is used as a battery voltage indicator. The consumer can be switched on/off
manually with the aid of the on/off button. Problems with poor contact, which may occur with
conventional mechanical switches due to vibration or oxidisation, are avoided. The on/off
switch also offers protection against discharge damage. If the battery voltage drops below
6 V, the on/off switch switches the voltage off automatically. It switches back on again as soon
as the voltage exceeds 6 V. The on/off switch does not have surge protection, but is able to
withstand an excess voltage of up to 20 V without damage.
This product is intended for indoor use only. Do not use it outdoors. Contact with moisture (e.g.
in a bathroom) must be avoided under all circumstances.
For safety and approval purposes, you must not rebuild and/or modify this product. Using the
