We have these foot switches that are suitable for some types of window machinery.
These are non latching switches and they have a safety catch to hold the item in place until the user pushes the catch out the way.
They are five way, 2 position, 1/4" valve body. The port sizes are 1/8".
They come with 3 x 4mm fittings at the back of the foot switch (alternative size fittings can be brought seperately - please call).
