Montgomery square buttons, often incorrectly called G&P, were made from the late 1960s through the early 1980s. These buttons are white squares with black edges, that light up off-white. Floor buttons usually have numbers printed on their faces, door open/close and alarm buttons have their functions printed in all caps. Call buttons usually have arrows similar to Innovation Universal.

Early elevators with these buttons lack a door close button, but later examples have them.

Due to the old age of many elevators with these fixtures, they are becoming rare as more elevators are modernized.

Select is a rare 1990s fixture which consists of a slightly concave clear plastic button. These somewhat resemble Innovation Pinnacle, and as a result, they are often mistakenly referred to as an older version of Pinnacle.

Select was offered in the 1990s, intended for high-end installations. Like Conventional, Select was custom made for Montgomery and Montgomery KONE by Innovation, and is paired with their key switches and dot-matrix indicators.

Select came in 5 different types:

• S/1: Button with a diecast braille inserted next to the button (used for call stations or operating panels)

• S/2: Button with an "engraved button identification" on the faceplate, no braille (used for call stations or operating panels).

• S/3: Button with an "engraved button identification" AND a die-cast braille insert on the plate (basically S/2 but with a braille) (S/3 was used for call stations or operating panels)

• S/4: Button with a wraparound braille that captured the entire button and halo, and has a similar appearance to Westinghouse/Schindler RT used for call stations or operating panels)

• H/5: Button with no braille (only on call stations)

Series 220 was Montgomery KONE's final standard fixture, replacing Vector in 1994.

Series 220 buttons consist of a black rectangle with rounded corners, and a smaller white rectangle in the middle (triangle on most call buttons). It features a red LED halo around the button and a wraparound label.

During the Montgomery KONE era, Series 220 was usually paired with Innovation lanterns and the red LED indicator, or, on rare occasions, the VFD indicator.

• Montgomery introduced a three-digit vacuum fluorescent (VFD) indicator in the early 1980s. This indicator is most commonly seen with Innovation fixtures, but also with Vector and A Series, and very rarely with EPCO or Series 220. It can be either dark blue or teal-green.

• In the early 1990s, Montgomery introduced a red dot-matrix LED indicator. The arrow is stationary on most of these, though some examples have a scrolling arrow. This was used with Innovation buttons and Series 220. This indicator was produced throughout the Montgomery KONE era, and used on some very early KONE elevators.

Armor

Montgomery used Armor circle buttons on some installations in the early 1980s. These Montgomery elevators are extremely rare, and usually not labeled as Montgomery.

EPCO

Montgomery used EPCO Flushline and Circleline buttons on some installations in the early 1980s. These are quite rare today. They usually have capacity plates with the "Globe & Parallelogram" logo.

Adams

Montgomery used Adams Survivor buttons on some installations in the 1980s.

Dewhurst

Most 1980s Montgomery elevators in Canada have Dewhurst buttons.
