Abstract
A soft touch switch comprises a switch housing, a first soft touch sensor, and a second soft touch sensor. The switch housing has an outer surface which is curved and an inner surface. The first sensor is disposed inside the switch housing adjacent a first portion of the inner surface, and the second sensor is disposed inside the switch housing adjacent a second portion of the inner surface. The first and second sensors are disposed in different planes inside the switch housing. The soft touch switch is especially suited for industrial applications such as punch presses and has enhanced safety, ergonomic, and freedom of installation features.
