The seal (10) comprises a one-piece molded cylindrical body having an open end (12), a closed end (16) , and a cylindrical side wall (14) . Outwardly projecting sealing ridges (26 and 18) are formed on the wall portion. Seal 10 is inserted into a bore (38) in a control panel (40) such that the sealing ridges contact the bore to seal out moisture, chemicals and other contaminants, and to retain the seal in the bore against upwardly directed pressure.

Seal for push-button switches

A bracket for attaching a handle to a surface has a main bore for receiving the handle. A secondary bore intersects the main bore and receives a set screw having a tapered midsection which tangentially engages the handle. Tightening the set screw advances the tapered midsection which acts as a wedge to press against the handle and maintain the handle firmly within the main bore.
