ABSTRACT:
A reed switch holder assembly for detecting the passage of a magnet adjacent the assembly. The assembly includes a reed switch and first and second terminal elements each including a lead-receiving ferrule and a portion for mechanical and electrical connection to a conductor. The ferrule has a spring finger for holding a lead of the reed switch which finger includes a portion extending transversely from the remainder of the ferrule. The reed switch holder of the assembly includes a base of one-piece molded thermoplastic construction and a cover of one-piece molded thermoplastic construction. The base and cover include a latching mechanism for holding the base and cover assembly which, in their assembled condition, define a central cavity for holding the envelope of the reed switch and a pair of side cavities for receiving the leads of the reed switch and the ferrules of the terminal elements. One side cavity extends to a first end of the holder and the other side cavity extends to the holder second end. The holder also has a window extending transversely from each side cavity for holding the finger portion of the corresponding ferrule. The holder also includes a mount for attaching the assembly to a mounting wall.
