Abstract
Abstract A tie-bar of variable length for mechanically linking a desired number of lamps (such as LEDs) includes dove-tailed channels with a "V-shaped" groove in each dove-tail channel. Each lamp is disposed in a housing having a compatible dove-tailed mounting channel designed to fit half of adjacent tie-bar channels on the tie-bar assembly. The "V-shaped" grooves are used to break the tie-bar to a desired length for mounting a required number of lamp housings.

Claim 1
Independent Claim
73 words
The assembly of at least one circuit board indicator lamp housing and a tie-bar for mounting a plurality of said lamp housings, said assembly comprising: a plurality of dove-tail channels provided at spaced locations along the length of said tie-bar, and said housing including a complementary shaped dove-tailed channel on a surface thereof adapted to be slidingly received between one half of each of an adjacent pair of said spaced tie-bar dove-tail channels.
Claim 2
Dependent Claim
73 words
The assembly of at least one circuit board indicator lamp housing and a tie-bar for mounting a plurality of said lamp housings, said assembly comprising: a plurality of dove-tail channels provided at spaced locations along the length of said tie-bar, and said housing including a complementary shaped dove-tailed channel on a surface thereof adapted to be slidingly received between one half of each of an adjacent pair of said spaced tie-bar dove-tail channels.
Claim 3
Dependent Claim
31 words
The assembly of claim 1 including a substantially V-shaped groove extending along the height of said tie-bar at each location spaced along said tie-bar corresponding to each of said dove-tailed channels.
Claim 4
Dependent Claim
36 words
The assembly of claim 1 wherein said housing includes a horizontal ledge formed and extending over the dove-tail channel therein for seating on top of said tie-bar when said housing is slidably received on said tie-bar.
Claim 5
Dependent Claim
