Abstract: An attachment for an electronic switch having an outlet tube in one embodiment includes a first clamp member including a pair of legs having respective hooks on ends thereof, and a second clamp member having a pair of locking pawls for locking engagement with the hooks, respectively. In a second embodiment the clamp members are identical with a leg and hook and a pawl on each member. The second clamp member having a pair of cavities in which the legs can be fitted, respectively, the first and second clamp members being connectable together to hold the outlet tube of the electronic switch therebetween.

Abstract: An electronic switch includes a detector head in the form of a rectangular parallelepiped having a detecting surface and connecting members disposed on a corner thereof including a surface opposite to the detecting surface, the connecting members being identical in shape when the detecting surface is oriented in either a forward or lateral direction, the connecting members being symmetrically arranged with respect to an edge of the detector head, a head joint having an end to which the detector head is connectable by the connecting members and also having a rotatable annular connector on an opposite end thereof, and a switch box having engagement means for slidable engagement with the annular connector of the head joint so that the head joint can be rotatably mounted on the switch box. The detecting surface can be oriented in all of lateral directions by rotating the head joint.
