The present invention relates to a push button switch 5 comprising a curved deformable contact element 4. The push button switch 5 comprises at least one first terminal point 1, at least one second terminal point 2, and at least one third terminal point 3. The deformable contact element 4 is switched between a first and a second state. In the first state the deformable contact element 4 connects the at least one first terminal point 1 with the at least one second terminal point 2 whereas there is neither contact between the at least one third terminal point 3 and the at least one first terminal point 1 nor between the at least one third terminal point 3 and the at least one second terminal point 2. In the second state the deformable contact element 4 connects the at least one first terminal point with the at least one third terminal point 3, whereas there is neither contact between the at least one second terminal point 2 and the at least one first terminal point 1 nor between the at least one second terminal point 2 and the at 1 least one third terminal point 3. This implies that the push button switch 5 is designed to be both normally closed and normally open.
