Abstract:
A safety edge switch (1) for a moving component of power driven equipment, comprising:an electrically conductive hollow profile made of elastomeric material having an inverted U-shaped mounting profile (2) and a rounded shell part (3) which extends laterally beyond said U-shaped mounting profile (2), an electrically conductive internal body part (4) within said shell part (3), said internal body part (4) including a plurality of laterally spaced strip-like projections pointing toward said shell part (3) including a central projection and a pair of laterally outer projections, said internal body part (4) and said shell part (3) being electrically conductive and, upon mutual contact, initiate a switching pulse for an interpretation unit, and a nonconductive intermediate layer (5) between said internal body part (4) and said mounting profile (2) which extends laterally beyond said laterally outer projections of said internal body part 4 and downwardly around the upper part of said U-shaped mounting profile (2) and to said shell part (3) whereby small lateral deformations of said shell part (3) do not initiate a switching pulse.
