<p>A membrane switch assembly comprises a support member (13) on which are provided a pair of membranes (10, 12) carrying aligned contacts (101, 121), the membranes (10, 12) being spaced apart by a separation membrane (11) having an aperture (111) in alignment with the aligned contacts. An actuator (200) is provided for selectively engaging the membrane (10) to cause the aligned contacts (101, 121) to contact one another through the aperture (111). At least one of the support member (13) and the membranes (10-12) has a number of deformations (115) for absorbing the impact of the actuator on the membrane (10) so as to reduce the noise generated thereby.</p> |
