Munich/Germany, 07 July 2011: The S 135 emergency switch from Schaltbau GmbH is installed inside the prototype of the electric Spyder from Broedersdorff & Koenzen GmbH. The company is a manufacturer and provider of electric drives. The emergency switch ensures immediate power interruption through manual actuation. As such, it contributes to the safety of the vehicle. The red knob has two defined positions: The contacts are closed during normal operation. In the event of an emergency, depressing the knob instantly opens the circuit, thereby powering down the vehicle.

A momentary action mechanism within the actuation system ensures that the power down procedure initiated is completed automatically. The emergency switch is intended for d.c. applications. To increase the permissible breaking current, circuit elements with permanent magnetic blowout are used. The emergency switch is suitable for conventional thermal currents of between 160 and 250 amperes. The mechanical life is 30,000 operations. The emergency switch is rounded off by a cylinder lock.
