Abstract
An electrical safety device of an electrical control or regulating system of a gear shifting mechanism, includes a microcomputer, a pulse processor with an integrated watchdog timer and an integrated analog/digital converter, a retriggerable monoflop, a noninverting power amplifier, an inverting power amplifier and a Schmitt trigger in each of the response lines from a positive voltage output and a negative voltage output of the power amplifiers to the microcomputer. This enables an electromagnetic control element of a gear shifting mechanism to be supplied with a monitored positive voltage as well as with a monitored negative voltage.
