<p>The tripping device (AE) is a separate movable unit containing a battery (BA) and a tripping push-button (TA). The operating device (BE) is also a separate movable unit containing a switch adapter (AD) connected to a driving device (WE). It is put on the switch in the device operative state. The driving device is operated by a manually tensioned mechanical energy store. The driving device is held in its ready to operate state by a locking device (SH, SK). When the push-button (TA) is pressed down, the battery is disconnected and a solenoid winding (RW) is de-energised, releasing the locking device (SH, SK). This brings the switch to the required position.</p> |
