Button switches
Button switches PKn-12 (with fixation) and PKn-13 (without fixation) make up the bulk of that sub-group of products. Those switches are used in production of gas-stoves: PKn-13 for electric kindling, and PKn-12 for oven illumination. In 2006 the button TUP (temperature regulator with a safety device) was developed which is also used in gas-stoves.
