This surface-mounting, roll-down shutter push button is galvanically isolated and is equipped with two plates to switch the electric motor in either direction. On the left-hand key, an upward-pointing arrow is imprinted at the bottom, and on the right-hand key, a downward-pointing arrow is imprinted at the bottom. The push button is to be mounted in a splashproof, surface-mounting box. The entire unit is splashproof which makes it extremely well-suited for use in damp areas and in demanding environments. Colour combination: light grey with dark grey button.
