TELE-SWITCHING (TELESWITCH)
1. FUNCTION OF A TELE-SWITCH
A
tele-switch is an electromagnetic device used to control a lamp or many lamps
from different positions. A tele-switch
can also be called a teleruptor.
Example:
Control of a lamp from three positions, stair-case, long corridors.

3. CIRCUIT DIAGRAM OF TELESWITCH
We distinguish two
circuits:
- The
command circuitry: The coil is supplied through the impulse from the push buttons.
- The utilization circuit: the contact « k » of tele-switch controls the lamps.

3.1. OPERATION OF A TELE SWITCH
– The first impulse supplies the coil K and actions the contact « k ».
– A second impulse supplies the coil K opens the contact « k ».
REMARK: The control circuit can be supplied with low voltage of 8 to 24 V using a step down transformer.
