    Abstract: An electrical switch panel including a switch actuating assembly is disclosed for intermittently altering the electrical condition of a switch. A base member is formed to include a plurality of chambers each dimensioned for receiving and retaining the electrical switch actuating assembly is positioned on a support member carrying the switch. An insulative tactile film is arranged on the base pad providing a touch area covering the chamber openings. An axially movable member disposed in the chamber is operable by movement of the film to engage a cantilever switch actuating member whereby the axial movement of the film transmitted through the axially movable member causes an amplified movement of the cantilever switch actuating member which is effective in altering the electrical condition of the switch.
