Abstract

The switch has a magnetisable core (20) and a coil (22) surrounding this, and wound from a multicore insulated condutor. The or each winding is arranged in a covering body (26) forming a radial support. The body may be formed through a cut-out (25) of a carrier of the trigger of the switch (1). Alternatively the body may be a separate support tube.
