The LRT-3A Lighted Rocker Tab board, with up to 16 tabs is used on organ consoles for stop and coupler controls (The image displayed only shows 13).
Description
Rocker tabs cost considerably less than movable drawknobs or tongue tabs. It is also simpler to light lamps than move tabs physically and the power requirements are much less.
The LRT-3A has two groups of eight sprung rocker tabs that are pressed momentarily at the bottom to turn a stop On, or at the top to turn it Off. A lamp indicates the On state.
The 16 switch contacts are arranged in a matrix with one row of eight tabs per group and boards may be paralleled for simpler wiring. Multiples of 8 tabs can be used this way with the Classic control system, or up to 128 tabs when connected to an MLRT-1 MIDI-control board.
Serially-driven lamps may be lit remotely from the organ’s serial control system or through an MLRT-1 MIDI controller board.
Each tab cover can be easily removed for engraving or access to the lamp.
Tabs are at 0.95-inch centres and the board mounts horizontally (or vertically) behind a panel of ¾-inch thickness using screws above and below.
LRT-3A boards may be butted end-to-end for longer rows with no gaps. They can be shortened to a minimum of four contiguous positions with multiples of four to eight butted together for installations requiring fewer than 16 in a block.
Features
Applications
The LRT-3A is intended to be used on organ consoles to provide multiples of 8 stop controls with indicator lamps. With a MIDI control board (MLRT-1) it will provide MIDI stop data for up to 128.
