摘要：The torch (1) has two contact springs (7) differently connected with electriccurrent by rotating a printed circuit board (8). A connecting device has an electroniccircuit (10) arranged between lighting units i.e. LEDs, and the springs. The springs transmitelectric current for signaling a logical condition to the electronic circuit. The electronic
circuit individually feeds the lighting units with continuous electric current or with currentpulses whose frequency is 20 cycles per second to 200 kiloHertz. The electronic circuitvaries the pulse-pause ratio depending on the logical condition.
