ABSTRACT:
A switch device comprising at least two switches (12, 13) connected in parallel in a first electric path; a timing device (3) for feeding at a required time, a switching impulse along a second electric path to the switches thereby switching at least one of them (12) to a conductive state so that current flows along the first path; and a transformer (18) having a primary (20) in the said first path and a secondary (17) in the said second path arranged so that the aforementioned current induces a further switching impulse or reinforces the first switching impulse thereby switching or assisting the switching of the other switch (13) to a conductive state.
