Abstract: A solenoid switch assembly adapted for use with internal combustion engine starter motors which includes a solenoid switch mounted within a housing such that the solenoid core reciprocates parallel to the electrical leads. The electrical leads are aligned with the solenoid core and extend from opposite sides of the housing to provide a generally "in-line" configuration. Preferably, the housing includes two interchangeable, mating housing sections. The solenoid switch elements are mounted within the housing without using individual fasteners for the separate elements.

Abstract: A modular tower and method of constructing same is provided in which successive tower sections are joined. Each tower section is comprised of several tubular columns. Certain column ends are crimped for insertion into other columns. A brace assembly having tubes which substantially encircle the columns in each tower section is provided, the tubes being positioned to encircle the column where the crimped section of one column is inserted into another column. The columns are rigidly secured together by bolting the brace assembly to each of the columns encircled by each brace tube. A mast support brace assembly is provided for supporting a mast which extends from the tower top. A mast guide brace is provided for connecting the top of the uppermost columns and guiding a mast supported by the tower.
