ABSTRACT:
A switch designed to be activated by touch contact has a switching chamber ith contact surfaces on opposite sides thereof. A flexible switching film carries one of the contact surfaces and is arched over one side of the chamber. In order to prevent an increase in length of the switching film due to climatic effects from leading to incorrect switching, the switching film has at least one punctiform or linear deformation placed so as to cause the film to arch away from the opposite side of the chamber.
