Abstract

An operating member including an actuating part movably mounted between a rest position and a switching position, a circuit board with an open contacting portion, a switching mat made of an elastic material disposed adjacent to the circuit board, and at least one contact pill formed on a side of the switching mat facing towards the circuit board, which cooperate in such a way that, in the switching position of the actuating part at the latest, the open contacting portion of the circuit board is closed by the contact pill, and where the switching mat moreover forms at least one tactile-feel dome which is associated with the contact pill, is elastically compressible by actuation of the actuating part in the direction of the switching position and which, in its initial position, defines a unilaterally open hollow volume in the switching mat, in order to cause a tactile feedback on the actuating part, where the contact pill is disposed outside the hollow volume defined by the tactile-feel dome.
