Electronic switch for micro interruptions in supply and ground lines up to 100 A.

The Toellner Micro-Switch TOE 9261 is the first choice for generating short interruptions in supply voltages and therefore ideally suitable for testing vehicle electrics according to standards.

Depending on the model, currents up to 100 A can be switched at a rated voltage of up to 60 V.

The TOE 9261 is applicable for the following tests according to the LV 124 and LV 148 automotive standards

• LV 124, E-10: Short interruptions
• LV 124, E-13: Pin interruption
• LV 148, E48-09: Short interruptions

There are many other industry standards based on LV 124 and LV 148 like VW 80000, GS 95024-2, VW 82148, etc. with power and signal line interruptions, where the Electronic Switch TOE 9261 can be applied.

While testing vehicle electric power systems according to standards, it is necessary to momentarily interrupt supply voltages. Using the Micro-Switch TOE 9261, switching operations between < 10 ?s and nearly unlimited duration are possible without problem.

Any voltage source of up to 60 V with appropriate current rating provides the supply voltage.

Using an external signal generator, the current flow can be interrupted using switch S 1. Discharging the load circuit is possible during the interruption of the load current by using another internal switch (S 2).

In addition, a configuration can be selected for interrupting the negative return line of the load (ground interruptions).

Four signal line switches (S 3 – S 6) additionally enable precise switching and interruption of signal and control lines in any current flow direction. Control of these switches is synchronous with S 1.
