C&K offers a number of tactile switch options for display control on electricity and gas meters. The KSC and KSE series are both sealed to IP67 to withstand harsh outdoor environments for many years. Both come in 6 mm x 6 mm packages with a number of actuator heights and the ability to customize the haptics. The KMS series can be used if side mounting is needed. With a footprint of 4.2 mm x 3.5 mm and a height of 1.4 mm, it also has a variety of actuation forces and is sealed to IP40. If high temperature or cycle life performance is not required, C&K offers the lower cost PTS645 and PTS647 with footprints of 6 mm x 6 mm and 4.5 mm x 4.5 mm respectively.
